[clang] Introduce SemaOpenMP (#88642)

This patch moves OpenMP-related entities out of `Sema` to a newly created `SemaOpenMP` class. This is a part of the effort to split `Sema` up, and follows the recent example of CUDA, OpenACC, SYCL, HLSL. Additional context can be found in #82217, #84184, #87634.
