cmd/go/internal/modfetch: fix Lookup, Import; add ImportRepoRev

- Explain Lookup and Import, module paths vs import paths.

- Add ImportRepoRev, because neither Lookup nor Import
  is appropriate for translating legacy versioning system configs.
  There's more to do in ImportRepoRev, but it's already more
  accurate than before.

- Drop the old ad-hoc logic about github/bitbucket/etc
  in favor of resolving source code hosts using the "go get" logic.
  This enables paths like git.apache.org/thrift.git/lib/go/thrift again.

- Structure $GOPATH/src/mod/cache a little more: make separate
  top-level directories mod/cache/download and mod/cache/vcs.

Fixes golang/go#23983.
Fixes golang/go#24687.
Fixes golang/go#25590.
Fixes golang/go#25654.
