Attachment: Bug 1704662 - Track number of preferred compositor surfaces found during scene building.

During PrimitiveList construction, keep track of the number of
primitives that prefer being a compositor surface (this will be
used in follow up patches to configure how many sub-slices of
a picture cache are needed).

Also:

• Reduce size of PrimitiveVisibilityFlags so we can in future
  store a z-index of sub-slice that a prim exists on during
  the visibility pass without bloating PrimitiveVisibility.
• Abstract tile_count since in future there won't be a
  single hashmap of tiles per picture cache slice.
