Add scene side discrete level of detail.
New node `LOD` for UI, and `LODManager` within `World` for automatically updating child visibilities based on distance from cameras.
1) Physics interpolated particles in global mode are specified in global space. In VisualServer they should therefore ignore local transform.
2) Additionally, the expected final_transform should be passed on to children, rather than the identity transform used on the local item.
3) Local bounds in hierarchical culling are fixed for items using identity transform, by calculating their local bound in local space from the global space particles.

Move VisualServer interpolation data out of Scenario and into VisualServerScene, so the interpolation data and enabled status is now common to all Scenarios.
Fix physics interpolation in multithreaded mode by ensuring tick and pre-draw are called.

Adds optional hierarchical culling to the 2D rendering (within VisualServer).
Each canvas item maintains a bound in local space of the item itself and all child / grandchild items. This allows branches to be culled at once when they don't intersect a viewport.

The bound Rect2 was previously incorrect because bone transforms need to be applied to verts in bone space, rather than local space. This was previously resulting in skinned Polygon2Ds being incorrectly culled.

Large groups of similar rects can be processed more efficiently using the MultiRect command. Processing common to the group can be done as a one off, instead of per rect.
Adds the new API to VisualServerCanvas, and uses the new functionality from Font, BitmapFont, DynamicFont and TileMap, via the VisualServerCanvasHelper class.

To allow maximum flexibility in the initial rollout, VisualServer functions were not bound in order to prevent compatibility issues if the API changed.
These functions are now bound to allow direct use from the VisualServer.
