  [clang][x86] Add constexpr support for BMI/TBM BEXTR intrinsics (#109577)

This is an initial patch for constexpr handling of the BEXTR intrinsics - the plan is to support all x86 bit manipulation intrinsics eventually (and then SSE/AVX intrinsics), but I wanted to treat this as an initial test patch.

Hopefully this will unstick #94161 as well.
