fix: Update navmeshes (#1229)

* re-add x and z checking for height

Now that we have better navmeshes, this will result in much better results and as such we can re-enable this check.

* Always run navmesh extraction

waste of time most of the time, but no other way to force update to the meshes easily.

* Navmeshes Version 2

- Add all missing zones
- Drastically improve several zones and their navmeshes, cleaning them up, making them more accurate and generally using more features of detour/recast.

* Update CMakeLists.txt

* update meshes

* Navmesh: Add pet cove navmesh

* Navmesh: Fix navmesh for fv
