* ATOM-15859 AuxGeom rendering in editor is too expensive
- The OrphanBuffer calls is the main reason that AuxGeom FP render is slow.
- Switched to use DynamicBuffer for buffers used in DynamicPrimitiveProcessor
- Added some profiling marks.
- Removed DynamicPrimitiveProcessor per view which was added because of OrphanBuffer can only be called once per frame.
