[AMDGPU] Fix register class constraints for si-fold-operands pass when folding immediate into copies (#131387)

Fixes https://github.com/llvm/llvm-project/issues/130020

This fixes an issue where the si-fold-operands pass would incorrectly
fold immediate values into COPY instructions targeting av_32 registers.

The pass now checks register class constraints before attempting to fold
the immediate.
