Subject: [PATCH 1/2] [DirectX] generate resource table for PSV part
Use DXILResourceWrapperPass to build the resource table.
Since DXILResourceWrapperPass operates on LLVM intrinsics
rather than DXIL operations, add addPreserved for DXILResourceWrapperPass
in the passes before DXContainerGlobals
Fixes #103275
