* This fixes the bug where many unbuilt interactions during registration would get corrected by blueprint construction scripts but the stationary light would continue to think it was built

1) Preshadows for self-shadow only primitives now correctly mask by the receiver and not the subject.
2) Self-shadow only objects are no longer included in whole scene shadows (view dependent whole scene shadows already worked).

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

ES2 emulation 'ShouldCache' hit proxy shaders.
Add static meshes to hitproxy drawing policy factory
Moved RenderHitProxies implementation out of FDeferredShadingSceneRenderer scope and split in to two so classes derrived from FSceneRenderer can call their respective InitViews(RHICmdList); in the correct place.

- FeatureLevelPreview menu option now instructs world to switch feature level. This triggers our WIP switching code which works a bit...
- Converted a few more GRHIFeatureLevel references over to point at the nearest convenient scene/sceneview
- Made GetRHIFeatureLevel a non-inlined function (breakpoints wouldn't stop on the inlined version) and #define'd GRHIFeatureLevel to point at the GMaxRHIFeatureLevel (i.e. back to old behaviour)
- Changes to FSystemTextures so that the global object gets initialized in a stack-y kind of way. You initialize at a feature level and it creates all textures needed up to that point. Subsequent initializes at a higher feature level will allocate the new ones needed but not the existing ones. Only behaviour change from this is that there was a single 1x1 texture created only for ES2 that I just let get created for every feature level to keep the "feature level stack" nature of things.

#ttp 331829 - Mobile Preview in Editor
#proj Engine
#branch UE4
#summary First pass of changes to remove GRHIFeatureLevel, allowing for multiple scenes with different feature levels to exist. First step towards dynamic mobile preview in the editor.
#change Added GMaxRHIFeature level which contains the highest supported feature level on this machine
#change Added a cvar "r.FeatureLevelPreview" which, when set to 1, enables a feature level selection in the quick settings menu. Not wired up to anything at the minute
#change Added a feature level variable to FScene, which is currently initialized to whatever GRHIFeatureLevel is. Accessed with GetFeatureLevel()
#change Added a helper accessor GetFeatureLevel() to FSceneView which gets the feature level from the relevant scene. Purely to reduce the amount of typing needed to get to a feature level
#change Many changes across the renderer to try and read the current feature level from the view or scene. Not everything is done yet, but this is almost all of the "easy" stuff. As there is still just a global feature level in the engine, nothing should change.
