OMP lowering: Regimplify 'OMP_CLAUSE_MAP_DECL_MAKE_ADDRESSABLE' DECLs [PR100280, PR104132, PR104133]
... by generalizing the existing 'gcc/omp-low.cc:task_shared_vars'.
Fix-up for commit 9b32c1669aad5459dd053424f9967011348add83
"OpenACC 'kernels' decomposition: Mark variables used in
synthesized data clauses as addressable [PR100280]".

PR middle-end/104133
gcc/
* omp-low.cc (task_shared_vars): Rename to
'make_addressable_vars'. Adjust all users.
(scan_sharing_clauses) <OMP_CLAUSE_MAP> Use it for
'OMP_CLAUSE_MAP_DECL_MAKE_ADDRESSABLE' DECLs, too.
