  [flang][OpenMP] Fix the privatization of common blocks (#200446)

Common block objects were being replaced on every privatization,
which caused errors for distinct privatizations on nested constructs.

Modifying a common block clone, instead of the original one, fixes the
issue. Cloning is limited to DSA flags because target mapping lowering
expects to find the common block address, through its defining
operation.

Fixes #178790
