The use-application-binary flag can be used to run a previously built
app package.

This reverts commit bd52a78c.

Slight cleanup of file locations in flutter_tools
to make it easier to see which files are responsible
for data reporting.

This is added as a dimension cd26

Reland "Added --dart-flags option to flutter run (#33924)"

This reverts commit 587687ee.

Adds two new custom analytics dimensions: run_target_os_version and run_target_mode_name that are sent with each invocation of flutter run and show up in Google Analytics as "screens".

This reverts commit 52ae9968.

This reverts commit faec4ca3.

Splits Xcode validation out of the iOS validator and into a stand-alone
validator, and groups the CocoaPods validator with that top-level
validator instead of the iOS validator. iOS now validates only the
iOS-specific tools (e.g., ideviceinstaller).

Reorganizes many of the associated clases so that those that are used by
both macOS and iOS live in macos/ rather than ios/. Moves some
validators to their own files as part of the restructuring.

This is the macOS portion of #31368

* Added support for authentication codes for the VM service.

Previously, a valid web socket connection would use the following URI:

`ws://127.0.0.1/ws`

Now, by default, the VM service requires a connection to be made with a
URI similar to the following:

`ws://127.0.0.1:8181/Ug_U0QVsqFs=/ws`

where `Ug_U0QVsqFs` is an authentication code generated and shared by
the
service.

This behavior can be disabled with the `--disable-service-auth-codes`
flag.
