[Impeller] Skip clip entity replay that cannot impact current clip. (#162113)

Fixes https://github.com/flutter/flutter/issues/161262

Sometimes we end up with clip replay entities that have clip depth
values substantially below the current depth. I suspect this is due to
either mismatched save/restore or a bug in our code. Update: this isn't
a bug/bug but its definitely a bug. We can have multiple clips per save,
but the restore will remove at most one from the record/replay.

If a clip has a depth value that is less than the current clip depth, it
cannot by definition impact anything that draws after it.
