cmd/pkgsite,internal: serve source

- Set up a /files endpoint on the server that can serve
  files from fs.FS implementations.

- Add source.FilesInfo, which returns a source.Info that links to
  /files paths. Use it to implement the SourceInfo method of the local
  ModuleGetters.

- Add a SourceFS method to the local MethodGetters so they can tell
  the server how to serve their files.

- Improve the tests in cmd/pkgsite to verify the source links.

Fixes golang/go#47982
