- Removed default shader platform parameter from GetGlobalShaderMap()
- Added an inline overload of GetGlobalShaderMap() that takes a feature level instead, and translates to the correct shader platform
- Cached feature level on FSceneView for faster access
- Cached shader map on FViewInfo for faster access
- Cached featurelevel/shadermap on rendering composition graph execution context, for faster access
Fixed a couple of crashes when switching feature level dynamically
- Needed to allow certain shader permutations to be generated if feature level was ES2, but still on a PC platform. (i.e. hitproxy shaders, and basepass shaders used by editor primitives system)

* Both paths still exist in code during this transition. The GetDynamicMeshElements path is currently disabled, enable with 'r.UseGetDynamicMeshElements 1'.
* DrawDynamicElements was called once per pass, all sorts of pass-specific cruft had leaked in along with short-term modifications of shared structures (vertex factories and material proxies). DrawDynamicElements was not const, so a bunch of 'update' type work had leaked in. Various PreRenderView implementations relied on the view being in the view family.
* GetDynamicMeshElements is called once in InitViews, and the resulting meshes are used in various passes. GetDynamicMeshElements is const and must not modify the proxy, update work should be pushed to the proxy from the game thread. GetDynamicMeshElements can be called on views that are not in the view family, which allows a proper view for shadow depth passes.
* View mode override functionality moved out of the individual proxies into a centralized place, ApplyViewModeOverrides
* GPU particles not working yet, FRecastRenderingSceneProxy not implemented

- Material editor preview nodes now work when the editor is in es2 mode
- Make editor primitives work in ES2 mode
- Fix slate font rendering in ES2 mode
- Remove ES2 shader de-gamma when in the editor
- Add a new linear sampler type for linear textures
- Various fixes for dynamic feature level switching
- When in an emulated feature level mode, display some text in the level editor viewport saying what feature level we're running
- Removed feature level parameter from USkeletalMesh::GetResourceForRendering. Not used for anything
- ParticleVertexFactoryPool is now creates feature level specific vertex factories.

Added new editor relevance flag to separate editor primitives that want to render in the stippled 'behind' mode.
Added pre/post edit & move callbacks to communicate whether we are currently interactively editing a brushes transform or parameters.
TTP# 329784 - EDITOR: BSP: Unable to see the geometry Wireframe when scaling down BSP.
