If a frame is scheduled by the time the delayed animator notify idle
task runs, then we should not call |NotifyIdle|.

Also, add a trace event in the task, to make it more clear in traces
when a notify idle call is coming from here (as opposed to
|Animator::AwaitVSync|).

So we can do golden test on PerformanceOverlay to avoid regression like

In 93452747 (#7642), //shell/platform/darwin:framework_shared was added
without the root flutter config, causing a build breakage in Fuchsia,
where flutter sits under //third_party/flutter as opposed to at the
root. The flutter root config is required to set -I../../third_party as
an include path.

This does several things:
- It adds CPU time on the IO thread, but avoids GPU time on the GPU
  thread.
- For images that are never drawn with mipmaps, it adds about 33%
  memory overhead. For images that are drawn with mipmaps, it saves
  an entire copy of the base level.
- It fixes https://github.com/flutter/flutter/issues/24517, which is
  a driver bug related to mip-mapping and cross-context images.

Overall, I think the tradeoff is good, but I'm curious to see what
benchmarks look like.

Avoids potential confusion due to the iOS framework already being called
Flutter.framework.

* Dynamic patching support for AOT mode.

* Cleanup.
