This feature makes it possible to workaround problems such as:
- long baking time due to heavy synchronization when parsing geometry
from mesh instances
- crash when freeing `NavigationMeshInstance` while baking
- errors when actively baking node tree is being detached from the
scene tree
Change the entire navigation system.
Remove editor prefix from nav mesh generator class. It is now used for baking
at runtime as well.
Navigation supports obstacle avoidance now with the RVO2 library.
Nav system will also automatically link all nav meshes together to form one
overall complete nav map.
