f87f8d4610 rescaling_pass: Fix rescaling Color2DArray ImageFetch offsets 
ImageFetch offsets for 2D array coordinates have a different composite size than the coordinates. The rescaling pass was not taking this into account.

Fixes broken shaders when scaling is enabled in Astral Chain, and likely other titles.

4790ba7839 spirv_atomic: Define U32x2 storage buffers for 64-bit storage atomics 
Some drivers do not support 64-bit atomics, and fallback to atomically modifying U32x2 vectors. This change ensures that U32x2 storage vectors are defined in the spir-v shader when 64-bit atomics are used.

Fixes a hang on some devices, notably Intel GPUs, when booting Pokemon Legends Arceus

66a0cedba3 shader: Fold integer FMA from Nvidia's pattern 
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
