Instead of always bridging all of the discovered modules of all of the queries, only do so for modules which are not already cached

#83050 changed the behavior to query every Clang module identifier imported from Swift, even for modules which may have previously been discovered as transitive dependencies of another query. This means we now have a lot of results coming in from Clang scanner queries which are redundant, and we bridge them all, all of the time, which adds up to a substantial amount of time.
Instead of always bridging all of the discovered modules of all of the queries, only do so for modules which have not already been cached at the time we record query results.
