While the mobile team wants to keep independent samples disbaled for PCD3D_ES3_1, it makes sense to move this as a platform dependent feature into the DDSPI configuration.

- Can specify multiple DPs and FriendlyNames now in the PreviewPlaform sections of a DDPI.ini file (separated by comma)
- Use the FriendlyName from the DDPI.ini directly in the platform preview menus, instead of counting on the friendly name of a ShaderPlatform
- IOS DDPI.ini as an example, with 3 DPs, generic IOS (what we had before), iPhone6S and iPadPro6

- add a new shader platform (SP_METAL_SIM) to support iOS Simulator specific compilation requirements
- update iOS sim #define WITH_SIMULATOR to WITH_IOS_SIMULATOR

Platforms that do support uniform buffer objects can now provide batched primitive data through UBO. There is a limit UBO range that can be accessed in shaders, so we group instances into batches that fit into this limit. Switch uses 64KB views, other platfroms16KB views. For each primitive we allocate 512Bytes and 256Bytes for instance. Mobile platforms that do not support UBO will use a desktop version of GPUScene.
There are a few things that still missing: Dynamic mesh passes, static lighting

* This should be used to guard any features that require explicitly accessing buffer or textures SRVs in vertex shaders

r.ShaderPipelines
r.Material.ExcludeNonPipelinedShaders
Both cvars are currently disable on WindowsEngine.ini which make them also disable when we cook for consoles. ExcludeNonPipelinedShaderTypes is currently used only at cooking time when we compile shaders which is currently returning false, since the value is disabled on windows. Making those cvars use FShaderPlatformCachedIniValue, will allow to have specific platform value when cooking for a specific target. Moving r.Material.ExcludeNonPipelinedShaders to the defaultengine.ini file to keep it disable for the moment and not affecting shader key string. Will enable it progressively on console later.
r.Shaders.RemoveUnusedInterpolators
Make that cvar platform agnostic, since it will be used in on other consoles eventually. Platforms supporting the stripping of unused interpolators will check the same flag (CFLAG_ForceRemoveUnusedInterpolators) to enable it. Since windows can run opengl, and stripping is not supported on that shader platform, add extra logic to exclude the flag.
-Make the RHISupportsShaderPipelines function access a real DDPI attribute and not just test if we are not on mobile. Will need this to be able to have stripping unused shader interpolators on Switch.

- GetFriendlyShaderPlatformName removed
- RHIShaderPlatformDefinitions.inl deleted
- Added FriendlyNames to all ShaderPlatforms in DDSPI
- MenuText now comes from FriendlyNames in DDSPI

Changed ShaderArchive, GlobalShaderCache, ShaderDebugInfo and Autogen to use ShaderPlatformName and not ShaderFormat when naming their output files.
