* Reland: [macos] add flavor options to tool commands

Adds --flavor option to flutter run and flutter build. Running against
preexisting devicelab flavor tests for feature parity between macOS,
iOS, and Android.

This relands #118421 by alex-wallen which was reverted in #118858 due to
the following test failures:

The bail-out with "Host and target are the same. Nothing to install."
added in `packages/flutter_tools/lib/src/commands/install.dart`
triggered failures in the following tests, which unconditionally attempt
to install the built app, which is unsupported on desktop since the
host and target are the same:

* https://logs.chromium.org/logs/flutter/buildbucket/cr-buildbucket/8791496218824259121/+/u/run_complex_layout_win_desktop__start_up/test_stdout
* https://logs.chromium.org/logs/flutter/buildbucket/cr-buildbucket/8791496218165602641/+/u/run_flutter_gallery_win_desktop__start_up/test_stdout

Fixes #64088

* Partial revert: eliminate install check on desktop

The original flavour support patch included a check that triggered a
failure when flutter install is run on desktop OSes. This was
intentional, since the host and target devices are the same and
installation is unnecessary to launch the app on currently-supported
desktop OSes.

Note that Windows UWP apps *do* require installation to run, and we used
to have an install command for those apps, though UWP is no longer
supported.

Since that part of the change was orthogonal to flavour support itself,
I'm reverting that component of the change and we can deal with it
separately if so desired.

This reverts commit 73096fd9.

This changes the default build architectures for Flutter macOS apps to
x86_64 and arm64. Previously, we manually excluded arm64 builds via the
EXCLUDE_ARCHS Xcode setting in Flutter's generated xcconfig file. This
eliminates setting EXCLUDE_ARCHS during the build and updates the
default architectures in the tool and in the macos_assemble.sh wrapper.

[flutter_tools] support code size tooling on iOS, linux, windows, macOS, and Android on Windows (#63610)

Adds support for size analysis on iOS, macOS, linux, and Windows - using an uncompressed directory based approach. The output format is not currently specified.

Adds support for size analysis on android on windows, switching to package:archive

Updates the console format to display as a tree, allowing longer paths. Increases the number of dart libraries shown (to avoid only ever printing the flutter/dart:ui libraries, which dominate the size)

Adds support for --bundle-sksl-path to windows, linux, macOS, and iOS.

Fixes #53115

Also combines experiments into extraGenSnapshot/ExtraFrontEndOptions. Allows providing --no-sound-null-safety to allow out of order migration and running.

When you run this, bash complains that `local` is only valid in functions. Gets rid of that extraneous warning.

Ensure --no-track-widget-creation is piped through android/macOS. Adds integration testing for iOS/android/macOS

Ensure iOS and android builds can be correctly cached. Use the performance-measurement-file to verify that all targets were skipped on the second invocation. This is only run on the flutter_gallery build.

This will allow experimenting with the remove to string transformer before we're ready to turn it on by default. This doesn't work for web yet since we use dart2js instead of the frontend_server for producing kernel

* 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
