  [DirectX] Implement lowering of llvm.dx.resource.samplebias to the SampleBias DXIL Op (#199745)

Fixes #192548

This PR implements the lowering of the `llvm.dx.resource.samplebias`
intrinsic to the `SampleBias` DXIL Op.

Although I reckon that other `lowerSample*` functions in
`DXILOpLowering.cpp` will have shared logic, this is the first one to be
implemented. Consolidating common logic between future `lowerSample*`
functions can be left to a later PR implementing the second or other
`lowerSample*` function.
