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 commit is empty and simply triggers a new build to open the tree.
Commit e9ca785106ddc672d945062758800bdf1dd0aa68 was re-built after a
succesful build; upload to the cloud storage bin failed.

Dart VM flags are passed to Flutter via an fml::CommandLine::Option that
looks something like:
{"dart-flags, "--max_profile_depth 1,--trace_service"}
We perform a prefix match to handle cases where Dart VM options take
arguments.
Adding the comment since in a recent review I found myself wondering why
we're using a prefix match to begin with. While the original author had
forgotten, the good news is, he wrote a test that covers this exact
case. This comment just removes one level of indirection for future
readers.
