This works provides better emulation on certain GS missing for shader invocation data + geometry pass fallback in qcom/turnip drivers, some of those were provided as community patch by @a.kamaltdinov; which was refined to address the requirements on forced gpu reads; which used to kill some performance on low end devices; now, the stability with some of the graphical problems have been addressed and balanced. Shuffle shaders (SHFFL) are not actually provided on QCOM and turnip drivers, so any game that previously required this stage draw, will now avoid being ignored and tax some performance based on the complexity of the stage draw from now on. This will also address partially some tessellation problems as well.
_Special Thanks:_
1.- @a.kamaltdinov (for the initial patch "early fix for nier" provided for #4325)
2.- @PavelBARABANOV (because the making the cherry-pick easier for a new PR)

Compilation and CMake fixes for both Windows on ARM and clang-cl, meaning Windows can now be built on both MSVC and clang on both amd64 and aarch64.
Compiling on clang is *dramatically* faster so this should be useful for CI.

Fold shaders doing "a * b + c" on integers from the pattern generated by
Nvidia's GL compiler.
On a somewhat complex compute shader it reduces the code size by 16
instructions from 2 matches on Turing GPUs.
On Intel as extracted from KHR_pipeline_executable_properties:
Before the optimization:
```
Instruction Count: 2057
Basic Block Count: 45
Scratch Memory Size: 14752
Spill Count: 232
Fill Count: 261
SEND Count: 610
Cycle Count: 11325
```
After the optimization:
```
Instruction Count: 2046
Basic Block Count: 44
Scratch Memory Size: 13728
Spill Count: 219
Fill Count: 268
SEND Count: 604
Cycle Count: 11367

Mostly fixing unused *, implicit conversion, braced scalar init,
fpermissive, and some others.
Some Clang errors likely remain in video_core, and std::ranges is still
a pertinent issue in shader_recompiler
