[clang][OpenMP] Implement `isOpenMPExecutableDirective` (#97089)

What is considered "executable" in clang differs slightly from the
OpenMP's "executable" category. In addition to the executable category,
subsidiary directives, and OMPD_error are considered executable.

Implement a function that performs that check.
