Attachment: Bug 1703737 - Only calculate prim_rect during dependency update for compositor surfaces.

This calculation was previously required, but is now only used by
the methods that set up a compositor surface. The early out check
for invalid prim_rect is covered by the clip chain rect test below.

This removes a per-prim map operation from a hot part of the frame
building visibility pass.
