CUDA: Fix compiler crash with unsized array field - nonuniformres-as-… (#8380)

…function-parameter.slang #8315

Root Cause:
CUDA compilation crashed with `assert failure:
!seenFinalUnsizedArrayField` because unsized arrays like
`RWStructuredBuffer<uint> globalBuffer[]` were not the final field in
generated parameter structs, violating the layout constraint in
slang-ir-layout.cpp.

Fix:
Extended `collectGlobalUniformParameters` to automatically reorder
struct fields for CUDA targets - regular fields first, unsized arrays
last. Other targets preserve original order.

Impact:
- Enables CUDA support for nonuniform resource indexing as function
parameters
- Zero impact on existing GLSL/HLSL/SPIRV targets
- Automatic handling - no manual parameter reordering required
