Original PR Author: @andywolff

Reviewed By: @gaaclarke

The original PR description is provided below:

Fixes #192992
Relands #191096
Fixes #190602
Fixes #162172

This PR relands #191096, which resolves the square corners regression in clipped backdrop filters. The original PR was reverted in #193189 due to test flakiness and order dependencies in CI, which were resolved and landed separately in #193497.

This is a pure reland.

Code Review

This pull request simplifies clip depth allocation and clip stack management in Impeller. Key changes include increasing Canvas::kMaxDepth to 1 << 24, streamlining depth tracking in Canvas::Save, Canvas::SaveLayer, and Canvas::Restore, and removing clip_height tracking from EntityPassClipStack. It also removes the unused transform parameter from ClipContents::Render and cleans up associated unit tests and mock dependencies. There are no review comments to evaluate, and I have no additional feedback to provide.
