78d98161 - [DirectX] Add `llvm.dx.resource.getdimensions.x` intrinsic and lowering to DXIL (#161753)

[DirectX] Add `llvm.dx.resource.getdimensions.x` intrinsic and lowering to DXIL (#161753) Introduces LLVM intrinsic `llvm.dx.resource.getdimensions.x` and its lowering to DXIL op `op.dx.getDimensions`. The intrinsic will be used to implement `GetDimension` for buffers. The lowering is using `undef` value since it is required by the DXIL format which is based on LLVM 3.7. Proposal update: https://github.com/llvm/wg-hlsl/pull/350 Closes #112982
