  [OpenMP] Ignore teams ICV setters in restricted contexts (#194428)

This patch prevents `omp_set_num_teams()` and
`omp_set_teams_thread_limit()` from updating teams-related ICVs when
called from restricted runtime contexts.

The non-implicit parallel-region case follows the OpenMP 5.1
restriction. The active `teams`-region case is handled defensively
because these ICVs are device-scoped and updating them during an active
`teams` region can affect later teams execution.

The calls now warn and return without updating the ICVs. 

Fixes #194426.
