e32ba332 - [SYCL][AMDGPU] Set amdgpu-flat-work-group-size for SYCL reqd_work_group_size (#22467)

[SYCL][AMDGPU] Set amdgpu-flat-work-group-size for SYCL reqd_work_group_size (#22467) AMDGPU verifier (added in 6794e31e894d) requires amdgpu-flat-work-group-size function attribute whenever reqd_work_group_size metadata is present. setFunctionDeclAttributes only handled OpenCL's ReqdWorkGroupSizeAttr; SYCL uses SYCLReqdWorkGroupSizeAttr which went through CodeGenFunction.cpp to emit the metadata but never set the function attribute, triggering the verifier error on amdgcn targets. Fixes CodeGenSYCL/reqd-work-group-size.cpp and check-work-group-attributes-match.cpp CMPLRLLVM-76303 Co-authored-by: Claude Sonnet 4.6 <noreply@anthropic.com> (cherry picked from commit 2fdfa4f13e90ca50d028360a844cb9e4d071fa61)
