Mulitple Gitea Doctor improvements (#10943)
* Add `gitea doctor --list` flag to list the checks that will be run, including those by default
* Add `gitea doctor --run` to run specific checks
* Add `gitea doctor --all` to run all checks
* Add db version checker
* Add non-default recalculate merge bases check/fixer to doctor
* Add hook checker (Fix #9878) and ensure hooks are executable (Fix #6319)
* Fix authorized_keys checker - slight change of functionality here because parsing the command is fragile and we should just check if the authorized_keys file is essentially the same as what gitea would produce. (This is still not perfect as order matters - we should probably just md5sum the two files.)
* Add SCRIPT_TYPE check (Fix #10977)
* Add `gitea doctor --fix` to attempt to fix what is possible to easily fix
* Add `gitea doctor --log-file` to set the log-file, be it a file, stdout or to switch off completely. (Fixes previously undetected bug with certain xorm logging configurations - see @6543 comment.)
