[flang][OpenMP] Stop tracking metadirective level in name resolution (#159945)
This was checked in the visitor for OmpDirectiveSpecification, and is
not necessary anymore: the early exit (in case of not being inside of a
METADIRECTIVE) performs the same actions as the code that was skipped,
except it does so through a different sequence of function calls. The
net result ends up being the same in either case.
The processing of the mapper and reduction specifiers inside of
OmpDirectiveSpecification is necesary for the declare directives on
WHEN/OTHERWISE clauses, so it's the early exit that needs to be removed.
In fact, when the DECLARE_MAPPER/REDUCTION use
OmpDirectiveSpecification, this processing will automatically take over
the handling of the contained specifiers.
