Brandon DeRosier 6e313cd781 [Impeller] Make StC work for Position+UV buffers. (flutter/engine#50900) ...

The accumulated fixes pulled out of the flag flip PR: https://github.com/flutter/engine/pull/50856

* Also fixes tests to make them resilient to StC being on/off.
* Fix blending for the cover draw.
* Default to depth=1 which is much more reasonable as depth=0 will never draw anything for cover draws. This allows enclosed subpass rendering cases like `Contents::RenderToSnapshot` for filter inputs to work by default and makes mistakes harder.
* Use depth+stencil attachments for `Contents::RenderToSnapshot` subpasses to allow for StC draws.
