Landscape export LOD uses MaxLOD from landscape actor by default
Sub-levels LOD generation will be still accessible when sub-level has landscape actor but user has no Simplygon available, in this case all geometry except landscape will be stripped

Disabled index buffer optimization when mesh has more than 50000 triangles. These won't be game meshes and the optimization time takes too long.
Also disabled adjacency buffer generation for high poly meshes. This would be better done as an import option.

* Requires a Movable Skylight + 'r.DistanceFieldGI 1' + 'r.GenerateMeshDistanceFields' project setting enabled
* Provides a single bounce of Diffuse GI with bounce distance limited by OcclusionMaxDistance (default 6m)
* Virtual Point Lights are placed from the directional light by ray tracing the scene's distance fields, normal comes from SDF gradient
* Currently only placing 128*128 VPLs up to 40m from camera
* VPLs light irradiance cache samples using hemispherical disk light model, indirect shadowing is provided by the same cone traces used for Distance Field AO
* Irradiance is computed only at irradiance cache points (max every 8 pixels) and interpolated to the rest of the pixels
* Hardcoded half grey material color for now, and poor performance due to brute force VPL lighting

- Greatly improved skeletal mesh importing by removing n^2 operation when combining vertices
- Added a cvar parameter to disable triangle order optimization (debugging purposes only)
