  [Flang][OpenMP] Use InsertionGuard in DataSharingProcessor

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.
