Parser would earlier alternate after finding the first
begin event, not it looks for pairs.

It appears nobody is benefitting from this logic, so we may as well not pay the cost.

* Make all of the driver interface public.

This is the second attempt at this; it should be better than before because the Logger interface, which conflicted in various places, no longer exists.

See #45733 for original attempt.

This reverts commit 0ce9206e (PR #45924).

This reverts commit f2445002.

We keep finding things that we've accidentally not made public. The
pattern we use elsewhere in the platform is to just export everything,
to avoid encouraging people from importing `src/` files directly.

* 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

* Added a composable waitForCondition Driver/extension API.

This reverts commit df2db4e5.

* Added SerializableWaitCondition for communicating between driver script on host and extension on device.

This reverts commit 8edc3f76.

This relands https://github.com/flutter/flutter/pull/35297

The followings have been done to fix the broken tests:
  1. Add `didSendFirstFrameRasterizedEvent` extension and its tests
  2. Wait for `didSendFirstFrameRasterizedEvent` instead of
     `didSendFirstFrameEvent` during start up tests
  3. Mark missed (probably newly added) start up tests as flaky
