Fix CUDA issues with texture reads and surface writes (#7780)
* Fix 1D texture reads in CUDA target
Fixes #7570: 1D surface writes don't work
The issue was that the Load function for read-only textures (hlsl.meta.slang lines 3629-3656)
only supported 2D and 3D textures for CUDA targets, causing 1D texture reads to fall through
to <invalid intrinsic>. This affected the srcTexture[tid.x] read operation in the reproduction case.
Changes:
- Updated static_assert to include SLANG_TEXTURE_1D support
- Added tex1DArrayfetch_int<T> for 1D array texture reads
- Added tex1Dfetch_int<T> for regular 1D texture reads

* Add 1D texture read support for CUDA target
- Add tex1Dfetch_int template specializations for float2, float4, uint, uint2, uint4
- Remove TODO comment about 1D PTX not being supported
- Enable 1D texture test in texture-subscript-cuda.slang
- Fix assembly code issues in original template specializations

* Update slang-cuda-prelude.h
* Fix texture3d ptx issue
* undo 1D texture changes
* Update hlsl.meta.slang
* Update hlsl.meta.slang
* Update hlsl.meta.slang
* Update hlsl.meta.slang
* Extend texture-subscript-cuda.slang test with uint and int format variants
Add test cases for newly supported texture formats in CUDA:
- 2D textures with uint, uint2, uint4
- 2D textures with int, int2, int4
- 3D textures with uint, uint2, uint4
- 3D textures with int, int2, int4
This ensures the texture subscript operations work correctly for all
the format variants added in the CUDA texture fixes.
