cmd/pkgsite,internal/fetch: improve startup experience
When a user tries to look at the documentation for a unit for the
first time, we process all the packages in the module. Kick off
goroutines to do that so that the modules' packages might be processed
by the time the user sees them. Also parallelize processing the
packages in the module. That brings processing std from about 8 seconds
to about 3 seconds.
