Specifying the `--enable-impeller` flag will switch the renderer to using
Impeller instead of Skia. On platforms where Impeller is not supported, this
flag is ignored.
The notion of the `flutter::SurfaceFrame` has been augmented. Now, in the
absence of a Skia surface to render to, the surface frame will render into a
display list instead.
Impeller variants of the context and surface variants have been added to
`shell/gpu` and `shell/platform`. The variants prepare surface frames that
don’t/can’t specify a Skia surface thus forcing the surface frame to render to a
display list instead. Then, in the submit callback, they forward the display
list ops to the Impeller display list dispatcher.
This scheme has been chosen as it requires the fewest updates to engine
internals which all depend on Skia data structures. Instead of updating all
call-sites to be Skia neutral, the display list interface itself is being made
graphics package agnostic.

This PR changes how embedder API's SendKeyData sends ui.KeyData to the framework. The packets are now sent over the existing platform messenger, reusing the entirety of its code path and functionalities while keeping the embedder API unchanged
This makes sure the frame timings recorder and vsync waiter implementations get
the correct refresh rate if or when it adjusts at runtime. This should be OK
because we'll only query the refresh rate when the display metrics actually
change, which is much less frequent than every frame. I experimented with an NDK
implementation in the previous patch, but that vastly restricts the API levels
we can support, and currently on API 30 and 31 it just calls Java methods
through JNI anyway.
I've refactored the way Display updates are reported so that AndroidDisplay can
just dynamically get the refresh rate correctly. These values are used by a
service protocol extension and by some Stopwatches on the CompositorContext.
