Also FViewInfo now accumulates a mask of all lightingprofiles used in a given view during the relevancy calculation.

options: Nop / Read / Write
added ensure() and check() to find bad usage patterns
this fixes DBuffer decal rendering, allows optimizations in the RHI (near hardware APIs like DX12 or consoles)
[CL 2505694 by Martin Mittring in Main branch]
Also add many explicit calls to CopyToResolveTarget to indicate the transition of a render target to be able to be used as an SRV. Soon to be replaced by a more specific RHI function.
Added r.CheckSRVTransitions for D3D11 on windows to check if any of these transition are missing.
Fixes a bug with RHIThreadFence when using PLATFORM_SUPPORTS_PARALLEL_RHI_EXECUTE
PLATFORM_SUPPORTS_PARALLEL_RHI_EXECUTE on PS4 now supports CMASK and HTILE enabled buffers.

Reflection captures work with feature level preview switching.
removed 'r.NoTiledReflections' support.

* Distance field building is now asynchronous and stored in the DDC separately from static mesh data.
* Added OcclusionMaxDistance and Contrast properties to Movable sky light
* Using the GBuffer normal instead of the generated distance field normal, fixes artifacts on two-sided materials and between modular pieces. Also saves about .7ms / 4.5ms
* Points in the distance field are only considered 'inside' the mesh if > 50% of all rays traced hit a backface. Most meshes can have a valid distance field generated with this heuristic. Meshes without a distance field representation can receive occlusion.
* Fortnite two-sided foliage with world position offset animation works fine now
* Using the resulting bent normal for diffuse lighting, improves consistency in occluded corners
* Resulting bent normal is also used to occlude skylight specular using an approximate cone-cone intersection, prevents leaking where SSR is not available
* Fixed stationary skylights not getting lightmap mixing
* Reflection captures now work with the movable skylight, which adds its diffuse contribution to IndirectIrradiance so their lightmap mixing works
* Added new show flag to visualize mesh distance fields, which ray traces through the distance fields and gives a sense of their shape

- 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.
