Rework GraphicBufferProducer

Browse Source 
This commit makes GraphicBufferProducer significantly more accurate by matching the behavior of AOSP alongside mirroring the tweaks made by Nintendo. 

It eliminates a lot of the magic structures and enumerations used prior and replaces them with the correct values from AOSP or HOS. 

There was a lot of functional inaccuracy as well which was fixed, we emulate the exact subset of HOS behavior that we need to. A lot of the intermediate layers such as GraphicBufferConsumer or Gralloc/Sync are not emulated as they're pointless abstractions here.
