Cache module-level scope resolution
PR #19306 made scope resolution significantly slower. I think part of the
reason for that is it removed some caching. This PR adds some caching for
module-level name lookups to make the process faster in the face of uses
and imports. That allows scope resolution to run slightly faster (in my
experiments) than before PR #19306.
The caching needed some adjustment in order to work with extern block
support. See also PR #12235 for history in this area.
