Improvements of releases list and tags list (#25859)

Follow #23465 and #25624

This PR introduces the following improvements:
- We do not need to call `GetTags` to get tags because tags have been
loaded by `RepoAssignment`

ef90fdbd1d/modules/context/repo.go (L663-L668)
- Similarly, the number of tags and releases also have been loaded by
`RepoAssignment`, so the related code has been removed from the
handlers. The query condition of `GetReleaseCountByRepoID` in
`RepoAssignment` has been changed to include draft releases.

ef90fdbd1d/modules/context/repo.go (L538-L551)
- `releasesOrTags` function has been removed. The code for rendering
releases list and tags list moved to `Releases` and `TagList`
respectively.
