Pokechu22 2f6953efb6 TextureConverterShaderGen: Set alpha to 1 on intensity formats if EFB lacks alpha
We were already doing this for non-intensity formats, but it seems like the same applies to intensity formats.

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 3d9b2aa005 VideoCommon: Migrate over to fmt
Migrates off the printf-based formatting where applicable.

Lioncash a5b28f1f07 ShaderGenCommon: Rename WriteFmt() to Write()
Now that we've converted all of the shader generators over to using fmt,
we can drop the old Write() member function and perform a rename
operation on the WriteFmt() to turn it into the new Write() function.

All changes within this are the removal of a <cstdarg> header, since the
previous printf-based Write() required it, and renaming. No functional
changes are made at all.

Lioncash 0f28f4049b VideoCommon/TextureConverterShaderGen: Convert over to fmt
Easily the most straightforward to convert over, given the lack of
significant formatting arguments.

Stenzek f269c4c798 EFB2Tex: Set alpha channel of Z24X8 copies to 1
Matches EFB2RAM.

Lioncash 149a97e396 VideoCommon: Remove unnecessary memset on ShaderUid instances.
Zero-initialization zeroes out all members and padding bits, so this is
safe to do. While we're at it, also add static assertions that enforce
the necessary requirements of a UID type explicitly within the ShaderUid
class.

This way, we can remove several memset calls around the shader
generation code that makes sure the underlying UID data is zeroed out.
Now our ShaderUid class enforces this for us, so we don't need to care about
it at the usage sites.

Stenzek eddde3e6c8 ShaderGen: Use interface blocks when geometry shaders are supported
We don't use explicit locations in OpenGL currently, so this breaks
when we use alternative names in the geometry shaders.

Stenzek 2165523fdc TextureConverterShader: Write EFB2Tex XFB copies with alpha value of 1
This way we don't end up with artifacts of the EFB's alpha values in
frame dumps. XFB copies loaded from RAM also set the alpha to 1, so this
will match.

Stenzek f74dbc794c EFB2RAM: Apply copy filter as a float coefficient after sampling
Using 8-bit integer math here lead to precision loss for depth copies,
which broke various effects in games, e.g. lens flare in MK:DD.

It's unlikely the console implements this as a floating-point multiply
(fixed-point perhaps), but since we have the float round trip in our
EFB2RAM shaders anyway, it's not going to make things any worse. If we
do rewrite our shaders to use integer math completely, then it might be
worth switching this conversion back to integers.

However, the range of the values (format) should be known, or we should
expand all values out to 24-bits first.

Stenzek 9e798eec94 Implement EFB copy filter and gamma in hardware backends
Also makes y_scale a dynamic parameter for EFB copies, as it doesn't
make sense to keep it as part of the uid, otherwise we're generating
redundant shaders.

Emmanuel Gil Peyrot d9c2de90c0 Reimplement EFB copy for intensity formats
This is the direct continuation of #5887, and removes the last usage of
the colmat matrix in EFB copy conversion shaders.

Jonathan Hamilton a38103afbf Fix GLES GPU texture conversion shader
GLES doesn't support C-style array initialisers, so stuff like:

Type var[2] = {
VALUE_A,
VALUE_B
};

isn't supported in GLES (it was added in
GL_ARB_shading_language_420pack).

The texture conversion shader used this, so would fail to compile on
GLES.

Emmanuel Gil Peyrot 85bb1d7bb0 VideoCommon: Reimplement texture format conversion
This fixes the rendering of the scan visor in Metroid Prime 2: Echoes,
as seen in https://fifoci.dolphin-emu.org/dff/mp2-scanner/

The alpha channel was off-by-one on Ivy Bridge due to the rounding
after multiplication with colmat.  This commit removes this matrix
altogether in most cases, making them simple GLSL swizzles.

Markus Wick 491c10ec96 VideoBackends: Use VideoCommon shader generators for efb2tex copies.
This will generate one shader per copy format. For now, it is the same
shader with the colmat hard coded. So it should already improve the GPU
performance a bit, but a rewrite of the shader generator is suggested.

Half of the patch is done by linkmauve1:
VideoCommon: Reorganise the shader writes.
