Pass 128-bit C-style enum enumerator values to LLVM

Pass the full 128 bits of C-style enum enumerators through to LLVM. This means that debuginfo for C-style repr128 enums is now emitted correctly for DWARF platforms (as compared to not being correctly emitted on any platform).

Tracking issue: #56071
