Refactor git module, make Gitea use internal git config (#19732)

Browse source 
* Refactor git module, make Gitea use internal git config, add safe.directory config

* introduce git.InitSimple and git.InitWithConfigSync, make serv cmd use gitconfig

* use HOME instead of GIT_CONFIG_GLOBAL, because git always needs a correct HOME

* fix cmd env in cmd/serv.go

* fine tune error message

* Fix a incorrect test case

* fix configAddNonExist

* fix configAddNonExist logic, add `--fixed-value` flag, add tests

* add configSetNonExist function in case it's needed.

* use configSetNonExist for `user.name` and `user.email`

* add some comments

* Update cmd/serv.go

* remove GIT_CONFIG_NOSYSTEM, continue to use system's git config

* Update cmd/serv.go

Co-authored-by: zeripath <art27@cantab.net>

* fix merge

* remove code for safe.directory

* separate git.CommonEnvs to CommonGitCmdEnvs and CommonCmdServEnvs

* avoid Golang's data race error
