Brandon DeRosier c4514370d7 [Flutter GPU] Add pipeline stencil config. (flutter/engine#55272) ...

Also adds a golden that depends on https://github.com/flutter/engine/pull/55270.
Resolves https://github.com/flutter/flutter/issues/142731.

Allow setting the stencil compare function, pass/fail operations, and read/write masks.

Flutter GPU has light "shader object" style programs, so all of the stencil configuration state can be set on the `RenderPass` at any time.

New simple golden that exercises stencil ops:
