- Context: Nanite support is automatically enabled on all meshes so want to expose quality controls and hide controls to enable/disable Nanite support.
- Expose Nanite quality settings in Static Mesh Editor.
- Hide Nanite menu in Content Browser / Static Mesh Actions.
- Hide option to enable Nanite in FBX import options.

This is an enum to say which target to reduce to for the fallback. It makes the default "Auto" which gives us more ability to change the default heuristic without needing to change uproperty defaults.
Along with this added r.Nanite.Builder.FallbackTriangleThreshold. Any mesh with source triangle count less than this threshold uses the source triangles directly for the fallback.

Changed Nanite visualization mode values from bits to consecutive numbers.
Removed temporary debug cvars r.Nanite.Streaming.Debug.TrimLockRegion and r.Nanite.Streaming.Debug.PersistPageUploadBuffer
Streamer now updates of cluster leaf flags using a custom shader that preserves the other flags, so we can now support multipe cluster flags.
Moved streaming shaders to separate files.
Format updates:
-Leaf flag subdivided into 3 different flags.
--Root leaf: Clusters that are leaves when only the root data is loaded. Needed for RootData visualization.
--Streaming leaf: Clusters that are leaves with the current streaming cut. Previous leaf semantics.
--Full leaf: Clusters that are leaves when everything is fully streamed in. Useful for VSM cache invalidation heuristics.
-Added root group flag for identifying groups that are fully inside the streaming cut (needed for RootData visualization).
-Added hierarchy depth to pages. Useful for bounding number of passes for multipass culling.

This aims to preserve the surface area during simplification. If area is lost, open boundary edges of the mesh are dilated to compensate. This is useful for foliage that tends to thin out in the distance if not enabled.
Also include misc fixes:
Collapses that completely remove disjoint triangles have an error of the area of what was removed.
Would not alias 0 and -0 verts due to binary comparison.

- If a static mesh is detected to use Nanite or a project is configured to use Virtual Shadow Maps and SM6 is not in the project settings, show a warning that SM6 needs to be enabled.
- Both cases only warn if the project was already configured to use a D3D platform.
- Added a UI option for enabling Nanite in project settings.

Removed redundant private include paths from build.cs files.
Fixed include paths to be relative to the private or public folders.
Hid or removed includes that reached into other private module folders.
Updated PublicInclude paths when necessary.

Artists can import/reimport(/new file)/remove nanite hi res data from the content browser context menu.
Artists can easily see in the static mesh editor if the nanite hi res data is generated or imported.
