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.

- Some static variables made it tricky, so added some support to make it simpler on users of the static variables

- 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

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
