  [flang][semantics] Add a flag to relax some of the semantic constraints on C_LOC (#195112)

This PR adds a flag that downgrades some of the semantic constraints on
C_LOC so that it can be used more like LOC. Without the flag behavior is
unmodified, with the flag the constraint that the address be object
pointer or target is removed. There are other constraints we might
consider relaxing, but I think this is a start.
