implement 3 configurable and toggleable framerate targets (#2159)
This pr allows for configuring the framerate target and adds support for two other framerate targets, a "fastforward" and "slowmo" target which can be enabled via either a toggle or holding a button.
this allows for supporting a more accurate framerate target and allows for users to slow down the speed of gameplay if they so desire

Improve calculation of light colors (#1967)
* maintain precision until all lights are calculated

fixes lugia on the soul silver title screen

* small optimization

* small note

* small cleanup/notes

shouldn't need to check that every time, since the variable shouldn't be able to overflow

* hw doesn't cap difflevel at 255

Should it cap at all?
Can vtx colors overflow...?

* diffuse level appears to be shifted right by 9

fixes some minor inaccuracies

* improve specular lighting a little

* small improvement to diffuse lighting

fixes a few off by ones
- finding by azusa

* small tweaks

* handle overflows of diffuse lighting properly

-credits to azusa once more

* attempt at improving specular lighting calcs

still far from correct, but its a start.
fixes: https://github.com/melonDS-emu/melonDS/issues/1545

* meh

* improve specular lighting further

* add notes

* theory: add half vec instead of subt 1

* implement azusa's specular lighting algorithm

* fix minor edge case with spec lighting

* give proper credit in comments

* fix some bugs/misc tweaks

* more quirky overflow/underflow handling

* fix a spec lighting edgecase

remove some redundant parentheses

* fix an edge case with light vector calcs

* spec recip uses a different calc for light dir?

also remove a check that shouldn't be mathematically possible to trigger

* nvm that thing i thought couldn't trigger was required

also move reciprocal calc into the light vector calc function since i might as well now ig

* replace a bunch of stuff with much *much* simpler algorithms

* misc cleanup

PARENTHESES WOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO

* leave a note abt shininess table's default value being incorrect

- Fixes a memory leak, as the cheat file wasn't cleaned up in the destructor

* Split `AREngine` and `ARCodeFile` apart

- Suitable for frontends that have their own way of storing cheats
- Store the cheats in `AREngine` in a `std::vector`
- Apparently cheats are _supposed_ to be executed each frame; I didn't understand this until recently

Compute shader renderer (#2041)
* nothing works yet

* don't double buffer 3D framebuffers for the GL Renderer
looks like leftovers from when 3D+2D composition was done in the frontend

* oops

* it works!

* implement display capture for compute renderer
it's actually just all stolen from the regular OpenGL renderer

* fix bad indirect call

* handle cleanup properly

* add hires rendering to the compute shader renderer

* fix UB
also misc changes to use more unsigned multiplication
also fix framebuffer resize

* correct edge filling behaviour when AA is disabled

* fix full color textures

* fix edge marking (polygon id is 6-bit not 5)
also make the code a bit nicer

* take all edge cases into account for XMin/XMax calculation

* use hires coordinate again

* stop using fixed size buffers based on scale factor in shaders
this makes shader compile times tolerable on Wintel
- beginning of the shader cache
- increase size of tile idx in workdesc to 20 bits

* apparently & is not defined on bvec4
why does this even compile on Intel and Nvidia?

* put the texture cache into it's own file

* add compute shader renderer properly to the GUI
also add option to toggle using high resolution vertex coordinates

* unbind sampler object in compute shader renderer

* fix GetRangedBitMask for 64 bit aligned 64 bits
pretty embarassing

* convert NonStupidBitfield.h back to LF only new lines

* actually adapt to latest changes

* fix stupid merge

* actually make compute shader renderer work with newest changes

* show progress on shader compilation

* remove merge leftover

* set a minimum and a better maximum for the pu region size

* fix pu logging

also tweak some logging a little more

* start is actually force aligned by size, oops

* small tweaks

* hopefully more clear code

ROMManager: optimise ROMIcon function
Precompute all 16 5-bit RGB palette colours into 8-bit RGBA to avoid
repeated and superfluous calculation within the nested loop at the
point of index lookup.

A speedup was observed, from ~7ms, to a consistent 1ms
(i.e. now practically instantaneous) through timing with
std::chrono::high_resolution_clock.

Also improve comprehensibility, by using meaningful names, where
appropriate, for loop counter variables.
