  Log Message:
  -----------
  [Flang] Add semantics checks for CrayPointer usage in DSA list (#123171)

Follow-up PR to fix the failure caused here:
https://github.com/llvm/llvm-project/pull/121028

Failure:
https://lab.llvm.org/buildbot/#/builders/89/builds/14474

Problems:
- Cray pointee cannot be used in the DSA list (If used results in segmentation fault)
- Cray pointer has to be in the DSA list when Cray pointee is used in the default (none) region

Fix: Added required semantic checks along the tests
Reference from the documentation (OpenMP 5.0: 2.19.1):
- Cray pointees have the same data-sharing attribute as the storage with
which their Cray pointers are associated.
