This PR adds `StructuredBuffer` to `HLSLExternalSemaSource.cpp`, by copying the logic from RWBuffer but just replacing the name with StructuredBuffer. The change now allows StructuredBuffers to be defined in HLSL, though they function the same as RWBuffers. Further work to apply the appropriate attributes that distinguish StructuredBuffers from other Buffer types will be deferred. This improves our position on https://github.com/llvm/llvm-project/issues/106189
