  [flang][OpenMP] Add semantic check for close nesting of `master` regions

This patch implements the following semantic check:
```
A master region may not be closely nested inside a work-sharing, loop, atomic, task, or taskloop region.
```

Adds a test case and also modifies a couple of existing test cases to include the check.
