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

* 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)

- 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.
