This allows to have up to 2**28 = 268435456 navmesh tiles and 2**20 = 1048576 polygons per each tile on scene.

Allow to cover all cells with exterior cell load distance = 3: https://streamable.com/2i02r
And with some more tweaks aitravel works for large distances: https://streamable.com/td24o

Do we really need it now? We do not update (and even do not render) actors outside the 7168 area anyway. Who is supposed to use these tiles?

Also I do not think we should rely on the exterior cell load distance.

So what did we decide to do with this PR?

What is the performance impact here?

As for me, it would be nice to have a some kind of simplified movement system (as in S.T.A.L.K.E.R., for example) for actors in inactive cells, rather than just use the huge scene for navmeshes (most of which will be unused 99% of time anyway).

So what should we do here?
Using the whole scene (outside of 3x3 cells grid) for navmeshes makes no sense.

There is no point to cover large areas with navmeshes at the moment.
