024dd569 - [HLSL] GetDimensions methods for buffer resources (#161929)

[HLSL] GetDimensions methods for buffer resources (#161929) Adds `GetDimensions` methods to all supported buffer resource classes (`{RW}Buffer`, `*StructuredBuffer`, `{RW}ByteAddressBuffer`). The method is implemented by calling one of both built-in functions `__builtin_hlsl_resource_getdimensions_x` and `__builtin_hlsl_resource_getstride` as described in proposal https://github.com/llvm/wg-hlsl/pull/350. The `__builtin_hlsl_resource_getstride` is implemented directly by Clang codegen by setting the buffer stride to the output variable. The `__building_hlsl_buffer_getdimensions` built-in function gets translated to LLVM intrinsic `@llvm.dx.resource.getdimensions.x`. Closes #112984
