Read Only Asset Editors: Automatically hide any custom menu and toolbar items in read only mode, with an opt in permission list for specific asset editors to selectively allow entries that are valid in read only mode

The edge selection code wasn't taking into account the start index for each section. It assumed that sections are arranged consecutively in the index buffer, which is not true in general.

Enabled by default. When disabled UVs are not lerped in the simplifier. This is useful when data stored in UVs isn't valid to interpolate, for example indexes.
Fixed long standing bug where locked boundary verts still would get attributes recalculated when taking part in an edge collapse. This results in them not matching when later merged with their neighbor, causing attribute discontinuities where they previously weren't. That will degrade further simplification, bloat vertex work, bloat vertex storage, and generally look worse.
Can reduce rendered vertex count by 14% and disk size by 3%.

Fix a crash in some asset editors when you force deleted an asset with pending changes and hit "cancel" on the save dialog

- 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.
