Pokechu22 5465775d11 Fix ambiguous uses of format_to
At least in MSVC (which is not restricted from targetting C++20), these can be resolved to either std::format_to or fmt::format_to (though I'm not sure why the std one is available).  We want the latter.

Pokechu22 fd2324e40a Fifo analyzer: Rename mipmap filter to half scale for EFB copies
The field itself is named half_scale, and it can be used for things unrelated to mipmaps, so reflecting that name in the fifo analyzer helps.

Scott Mansell f5c550e9cb Delay singlecore gpu interrupts
Fixes Bomberman Jetters in single core mode.

When single core mode pauses the CPU to execute the GPU
FIFO it greedily executes the whole thing. Before this commit,
Finish and Token interrupts would happen instantly, not even
taking into account how long the current FIFO window has
taken to execute. The interrupts would be effectively backdated
to the start of this execution window.

This commit does two things: It pipes the current FIFO window
execution time though to the interrupt scheduling and it enforces
a minimum delay of 500 cycles before an interrupt will be fired.

Scott Mansell 9fa26624b0 BPMemory: Refactor/consolidate TexUnit Addressing
Currently the logic for addressing the individual TexUnits is splattered all
across dolphin's codebase, this commit attempts to consolidate it all into a
single place and formalise it using our new TexUnitAddress struct.

Pokechu22 1640fa9096 Remove note about anisotropic filtering requiring edge LOD
This was added because YAGCD's info on MAXANISO (near TX_SETMODE0 in Section 5.11.1) claims it's the case, but Extrems says it does work.  I haven't tested anything myself, and dolphin still does not actually implement anisotropic filtering based on this field.

Pokechu22 df81210e96 Use formatters in GetBPRegInfo; add missing commands
BPMEM_TEV_COLOR_ENV + 6 (0xC6) was missing due to a typo.  BPMEM_BP_MASK (0xFE) does not lend itself well to documentation with the current FIFO analyzer implementation (since it requires remembering the values in BP memory) but still shouldn't be treated as unknown.  BPMEM_TX_SETMODE0_4 and BPMEM_TX_SETMODE1_4 (0xA4-0xAB) were missing entirely.

Pokechu22 70f9fc4e75 Convert BPMemory to BitField and enum class
Additional changes:
- For TevStageCombiner's ColorCombiner and AlphaCombiner, op/comparison and scale/compare_mode have been split as there are different meanings and enums if bias is set to compare.  (Shift has also been renamed to scale)
- In TexMode0, min_filter has been split into min_mip and min_filter.
- In TexImage1, image_type is now cache_manually_managed.
- The unused bit in GenMode is now exposed.
- LPSize's lineaspect is now named adjust_for_aspect_ratio.

Lioncash 3f210836ad Compiler: Rename __forceinline define to DOLPHIN_FORCE_INLINE
This is much better as prefixed double underscores are reserved for the
implementation when it comes to identifiers. Another reason its better,
is that, on Windows, where __forceinline is a compiler built-in, with
the previous define, header inclusion software that detects unnecessary
includes will erroneously flag usages of Compiler.h as unnecessary
(despite being necessary on other platforms). So we define a macro
that's used by Windows and other platforms to ensure this doesn't
happen.

Lioncash 03414e8e84 Common: Add header for compiler-specifics
Instead of globbing things under an ambiguous Common.h header, move
compiler-specifics over to Compiler.h. This gives us a dedicated home
for anything related to compilers that we want to make functional across
all compilers that we support.

This moves us a little closer to eliminating Common.h entirely.

Stenzek 260d5b7aa7 BPMemory: Handle fog configuration where both A and C are infinity/NaN
The console appears to behave against standard IEEE754 specification
here, in particular around how NaNs are handled. NaNs appear to have no
effect on the result, and are treated the same as positive or negative
infinity, based on the sign bit.

However, when the result would be NaN (inf - inf, or (-inf) - (-inf)),
this results in a completely fogged color, or unfogged color
respectively. We handle this by returning a constant zero for the A
varaible, and positive or negative infinity for C depending on the sign
bits of the A and C registers. This ensures that no NaN value is passed
to the GPU in the first place, and that the result of the fog
calculation cannot be NaN.

N.E.C c3a57bbad5 Video: Clearly separate Texture and EFB Copy formats
Improve bookkeeping around formats. Hopefully make code less confusing.

- Rename TlutFormat -> TLUTFormat to follow conventions.
- Use enum classes to prevent using a Texture format where an EFB Copy format
  is expected or vice-versa.
- Use common EFBCopyFormat names regardless of depth and YUV configurations.

comex 65af90669b Add the 'desynced GPU thread' mode.
It's a relatively big commit (less big with -w), but it's hard to test
any of this separately...

The basic problem is that in netplay or movies, the state of the CPU
must be deterministic, including when the game receives notification
that the GPU has processed FIFO data.  Dual core mode notifies the game
whenever the GPU thread actually gets around to doing the work, so it
isn't deterministic.  Single core mode is because it notifies the game
'instantly' (after processing the data synchronously), but it's too slow
for many systems and games.

My old dc-netplay branch worked as follows: everything worked as normal
except the state of the CP registers was a lie, and the CPU thread only
delivered results when idle detection triggered (waiting for the GPU if
they weren't ready at that point).  Usually, a game is idle iff all the
work for the frame has been done, except for a small amount of work
depending on the GPU result, so neither the CPU or the GPU waiting on
the other affected performance much.  However, it's possible that the
game could be waiting for some earlier interrupt, and any of several
games which, for whatever reason, never went into a detectable idle
(even when I tried to improve the detection) would never receive results
at all.  (The current method should have better compatibility, but it
also has slightly higher overhead and breaks some other things, so I
want to reimplement this, hopefully with less impact on the code, in the
future.)

With this commit, the basic idea is that the CPU thread acts as if the
work has been done instantly, like single core mode, but actually hands
it off asynchronously to the GPU thread (after backing up some data that
the game might change in memory before it's actually done).  Since the
work isn't done, any feedback from the GPU to the CPU, such as real
XFB/EFB copies (virtual are OK), EFB pokes, performance queries, etc. is
broken; but most games work with these options disabled, and there is no
need to try to detect what the CPU thread is doing.

Technically: when the flag g_use_deterministic_gpu_thread (currently
stuck on) is on, the CPU thread calls RunGpu like in single core mode.
This function synchronously copies the data from the FIFO to the
internal video buffer and updates the CP registers, interrupts, etc.
However, instead of the regular ReadDataFromFifo followed by running the
opcode decoder, it runs ReadDataFromFifoOnCPU ->
OpcodeDecoder_Preprocess, which relatively quickly scans through the
FIFO data, detects SetFinish calls etc., which are immediately fired,
and saves certain associated data from memory (e.g. display lists) in
AuxBuffers (a parallel stream to the main FIFO, which is a bit slow at
the moment), before handing the data off to the GPU thread to actually
render.  That makes up the bulk of this commit.

In various circumstances, including the aforementioned EFB pokes and
performance queries as well as swap requests (i.e. the end of a frame -
we don't want the CPU potentially pumping out frames too quickly and the
GPU falling behind*), SyncGPU is called to wait for actual completion.

The overhead mainly comes from OpcodeDecoder_Preprocess (which is,
again, synchronous), as well as the actual copying.

Currently, display lists and such are escrowed from main memory even
though they usually won't change over the course of a frame, and
textures are not even though they might, resulting in a small chance of
graphical glitches.  When the texture locking (i.e. fault on write) code
lands, I can make this all correct and maybe a little faster.

* This suggests an alternate determinism method of just delaying results
until a short time before the end of each frame.  For all I know this
might mostly work - I haven't tried it - but if any significant work
hinges on the competion of render to texture etc., the frame will be
missed.

Tony Wasserka 1d23c2ca8b GPU: Only load the relevant color components upon writes to the tev color registers.
The other two components need not be valid upon write, hence loading them results in glitches.
