internal/frontend: separate fetch and 404 logic into fetchserver

ServeFetch and ServePathNotFoundPage only work when a postgres
database is present. Separate them out into a different fetchserver
type which can be moved into a different package (in a followup cl).
This will allow their behavior, which is not used by cmd/pkgsite, to
be removed from that server. More importantly, their tests, which
depend on a real postgres database can be separated from the tests of
package internal/frontend.

For golang/go#61399
