Refactor branch/tag selector to Vue SFC (#23421)

Follow #23394

There were many bad smells in old code. This PR only moves the code into
Vue SFC, doesn't touch the unrelated logic.

update: after
https://github.com/go-gitea/gitea/pull/23421/commits/5f23218c851e12132f538a404c946bbf6ff38e62
, there should be no usage of the vue-rumtime-compiler anymore
(hopefully), so I think this PR could close #19851
