  [Flang][OpenMP] Use InsertionGuard in DataSharingProcessor (#97562)

This patch removes the introduction of `fir.undef` operations as a way
to keep track of insertion points inside of the `DataSharingProcessor`,
and it replaces them with an `InsertionGuard` to avoid creating such
operations inside of loop wrappers.

Leaving any `fir.undef` operation inside of a loop wrapper would result
in a verifier error, since they enforce strict requirements on the
contents of their code regions.
