  Log Message:
  -----------
  [flang][OpenMP] Reland Fix copyprivate semantic checks (#95799) (#101009)

There are some cases in which variables used in OpenMP constructs
are predetermined as private. The semantic checks for copyprivate
were not handling those cases.

Besides that, shared symbols were not being properly represented
in some cases. When there was no previously declared private
(implicit) symbol, no new association symbols, representing
shared ones, were being created.

These symbols must always be inserted in constructs that may
privatize the original symbol: parallel, teams and task
generating constructs.

Fixes #87214 and #86907
