  [Frontend][OpenMP] Follow compound construct clause restrictions (#107853)

This patch removes from the list of allowed clauses for a handful of
compound constructs those that are specifically disallowed by the OpenMP
spec. In particular, the following restrictions are followed:
- (regarding combined constructs) If _directive-name-A_ is `target`, the
`copyin` clause must not be specified.
- (regarding composite constructs) If _directive-name-A_ is
`distribute`, the `ordered` clause must not be specified.

These restrictions are listed in the OpenMP Specification version 5.2,
sections 17.4 and 17.5. Since it's a similar case as PR #90754, I'm
adding people involved in that decision as reviewers here.
