Brandon DeRosier 666563a554 [Impeller] Add Impeller Metal support in the embedder API (flutter/engine#42411) ...

Part of https://github.com/flutter/flutter/issues/112230.

Now seemed like the right time to sneak this in:
* We have large desktop refactors on the horizon (multi-window).
* We're starting to land optimizations that complicate the surface behavior such as wide gamut and dirty regions.
* We have plans to migrate the iOS embedder to use the embedder API (https://github.com/flutter/flutter/issues/112232).
