* Relicense Shrine demo to match rest of repository

The Shrine demo was Apache-licensed. The code was mostly
Google-written, with contributions from:

 - Michelle Dudley (@michdud)

 - Abhijeeth Padarthi <rkinabhi@gmail.com> (@rkinabhi)

 - @a14n

I contacted all three, and they confirmed their approval for this
change, as described below.

* Remove shrine loophole from license checker.

* f61bec846 Pass "null" when copy data is null to iOS pasteboard.string (flutter/engine#14046)

* 268107d2f fixing the method call for testing semantics (flutter/engine#14056)

* 35937eb31 Roll src/third_party/dart 134e0e28cd..96e7a4ff30 (38 commits) (flutter/engine#14058)

* 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

This appears to have been inadvertently added in #37497 (333c9618).

The code in question already exists in `_PlatformViewGestureMixin`, which
`PlatformViewRenderBox` (where it was added) mixes in.

Removes an unnecessary leading underscore from a parameter name. The
parameter type is library private, but parameters cannot be 'private'.

This PR adds TargetPlatform.macOS to the TargetPlatform enum. This allows us to begin implementation of some adaptive UI based on which target platform is desired.

I haven't updated the tests here, that will come in a follow-up PR.
