Brandon DeRosier 7105fd1909 [Impeller] Reland 2: Implement draw order optimization. (flutter/engine#54268)
This time for sure!

For each clip scope, draw opaque items in reverse order and
translucent/backdrop-independent items in their original order
afterwards. Clips are treated as translucent by the parent scope.

Respects clips, subpass collapse, and the clear color optimization.
