IMPALA-4465: Don't hold process wide lock while serializing Runtime Profile in GetRuntimeProfileStr()

This patch changes the code so that the query_exec_state_map_lock_
is not held while serializing the RuntimeProfile, since that is a
pretty expensive operation and happens at least once per query. This
change makes a lot of client calls have less lock contention including
Webserver calls and query registration/unregistration.
