Refactor legacy git init (go-gitea#20376)

* merge `CheckLFSVersion` into `InitFull` (renamed from `InitWithSyncOnce`) * remove the `Once` during git init, no data-race now * for doctor sub-commands, `InitFull` should only be called in initialization stage Co-authored-by: zeripath <art27@cantab.net> Co-authored-by: Lunny Xiao <xiaolunwen@gmail.com>
