02aacc4c - Reland: [OpenMP][clang] 6.0: num_threads strict (part 1: host runtime) (#147532)

Reland: [OpenMP][clang] 6.0: num_threads strict (part 1: host runtime) (#147532) OpenMP 6.0 12.1.2 specifies the behavior of the strict modifier for the num_threads clause on parallel directives, along with the message and severity clauses. This commit implements necessary host runtime changes. Reland https://github.com/llvm/llvm-project/pull/146403. After manual testing on a gfx90a machine, I could not reproduce the failing test, which makes it even more likely that the test has just been flaky. (Or at least that it's not an issue related to this patch.)
