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)

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.

* Still disabled as Metal requires a horrible workaround/hack
* Remove GSupportsGSRenderTargetLayerSwitchingToMips workaround

- 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)

- Inverse was one of the main reasons of crashes via lots of functions. Seems making default Inverse to be safer version seems better.

* 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
