FlutterCommand.runCommand subclasses can optionally return a FlutterCommandResult which is used to append additional analytics.
Fix flutter run timing report and add a bunch of dimensional data
`adb` can sometimes hang, which will in turn hang the Dart isolate if
we're using `Process.runSync()`. This changes many of the `Device` methods
to return `Future<T>` in order to allow them to use the async process
methods. A future change will add timeouts to the associated calls so
that we can properly alert the user to the hung `adb` process.
This is work towards #7102, #9567
Also, defer to test package for throttling (this will require a test
package update as well).
Also, add a lot more instrumentation to --verbose mode for tests, and
fix minor trivial things here and there, and add error handling in
more places.
Also, refactor how coverage works to be simpler and not use statics.
