config: add automatic closing to submaps (#11760)

* Allow submaps to auto reset to parent.

* Really should be a stack instead.

If hyprlang would allow for { } i would be so happy.

* Fixed: Somewhat better way to do it..

Lets you define what submap you want to go to instead.

* squash! Fixed: Somewhat better way to do it..

* God i hate cf..

* Force clang-format on the whole thing..

* Removed {}.

* Added tests

Tests and reset fix.
