[Openmp-commits] [openmp] [OpenMP] Add target to build OpenMP runtime (PR #189557)

[Jan Patrick Lehr via Openmp-commits]

https://github.com/jplehr created https://github.com/llvm/llvm-project/pull/189557

This adds a top-level target to build the OpenMP runtime, similar to what was done in https://github.com/llvm/llvm-project/pull/186099 for the Offload runtime.

Having this top-level target enables us to execute the build in the pre-commit CI as shown in https://github.com/llvm/llvm-project/pull/174955 (I actually just cherry-picked the commit from that branch)
