Brandon DeRosier 8870181d07 [Impeller] Manage the onscreen stencil in EntityPass (flutter/engine#41563) ...

Moves onscreen stencil management from the surface to EntityPass for
Metal and Vulkan. EntityPass has enough context to set up the stencil
optimally.

Also forces us to fail loudly when the supplied stencil is set up in a
way that can't be used for rendering the pass on GLES.

- On Vulkan, when we're blitting, we don't need to set up a onscreen
stencil attachment at all.
- And on both Vulkan and Metal, the onscreen stencil can be transient
when no pass reads are necessary (fixes the benchmark regressions
introduced by https://github.com/flutter/engine/pull/41509).
