[DirectX] Add isinf f16 emulation for SM6.8 and lower (#156932) 
fixes #156068

- We needed to add a new sub arch to the target tripple so we can test
that emulation does not happen when targeting SM6.9
- The HLSL toolchain needed to be updated to handle the conversion of
strings to enums for the new sub arch.
- The emulation is done in DXILIntrinsicExpansion.cpp and needs to be
able to convert both llvm.is.fpclass and lvm.dx.isinf to the proper
emulation
- test updates in TargetParser/TripleTest.cpp, isinf.ll, is_fpclass.ll,
and DXCModeTest.cpp
