Replace sync.Map with normal maps (#18584)

Browse Source 
* Replace `sync.Map` with normal maps

- These maps aren't being used in any kind of concurrent read/write and
thus don't need `sync.Map` and can instead use normal maps.
- Special thanks to dachary.
- Added in: https://github.com/go-gitea/gitea/pull/6290

* Remove unannounced feature
