1. Bug 1629704 - Rotate vertex data textures per frame. r=Bert,kvark …

   On some (primarily older, integrated) drivers, we see significant
   time in CPU stalls during updates to the vertex data textures.
   
   As a short term fix, this patch creates an array of vertex data
   textures, and rotates which set of them are in use each frame.
   
   There are better long-term options (such as porting the GPU cache
   scatter method, or perhaps using UBO/SSBOs here), but this is a
   simple workaround for now.

2. Bug 1629672 - Move prim_origin from instance to template. r=Bert,kvark …

   Previously, the prim origin needed to be stored in the prim
   instance, to avoid picture cache invalidations. With support
   for external scroll offset, this is no longer necessary.
   
   This simplifies some of the code paths, and reduces the size
   of primitive instances.
