Brandon DeRosier 716c6afba4 [Impeller] Skip rect clips that do nothing. (flutter/engine#43948) ...

Resolves https://github.com/flutter/flutter/issues/131100

* Skip rect clips that we know won't further restrict the clip shape.
* Don't append clips to enforce subpass bounds. We currently don't collapse passes when subpass clips are added anyhow, so just a restriction to subpass collapsing in order to keep the current behavior intact.
* Small refactor to reduce confusion: Just place the subpass bounds limit into `EntityPass` itself instead of the delegate.

Built on https://github.com/flutter/engine/pull/43946 (because iOS currently fails validation without it).
