Prior to this fix, `_TaskRunner.run` would immediately cleanup the
keep-alive port once the task completed, which would result in the
isolate shutting down as soon as the task result was returned from
`ext.cocoonRunTask` callback in the form of a
`ServiceExtensionResponse`. Since the service extension response is
processed by the service isolate, it was possible for the VM to start
shutting down before the service isolate could send the task result data
back to the task runner.
This change introduces a new service extension,
`ext.cocoonTaskResultReceived`, that the task runner invokes after it
receives the task result from `ext.cocoonRunTask`, notifying the task
process that it can close the keep-alive port and shutdown.

* [dev] Don't use await for on stdout and stdin; pass local engine argument
1) Don't use await for on stdout followd by await for on stderr.
This can cause nothing to happen. E.g. if one didn't do something
like `flutter pub upgrade` dev/automated_tests and the version in the
old one was pre-nnbd (but flutter itself use lots of nnbd stuff) lots
of errors would be emitted, but because we basically only listen to
stdout nothing will happen (deadlock once stderr buffer runs out).
Note that it still awaits the exit-code below.
2) Pass --local-engine (if given) so there won't be any crashes because
of that.
* Update project.pbxproj files to say Flutter rather than Chromium
Also, the templates now have an empty organization so that we don't cause people to give their apps a Flutter copyright.
* Update the copyright notice checker to require a standard notice on all files
* Update copyrights on Dart files. (This was a mechanical commit.)
* Fix weird license headers on Dart files that deviate from our conventions; relicense Shrine.
Some were already marked "The Flutter Authors", not clear why. Their
dates have been normalized. Some were missing the blank line after the
license. Some were randomly different in trivial ways for no apparent
reason (e.g. missing the trailing period).
* Clean up the copyrights in non-Dart files. (Manual edits.)
Also, make sure templates don't have copyrights.
* Fix some more ORGANIZATIONNAMEs
