Require repo scope for PATs for private repos and basic authentication (#24362) (#24364)

Backport #24362 by @jolheiser

> The scoped token PR just checked all API routes but in fact, some web
routes like `LFS`, git `HTTP`, container, and attachments supports basic
auth. This PR added scoped token check for them.
