* 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

No code changes, just comments: I spell-checked all the comments in the repo.

* implicit-casts:false on flutter_tools/lib

* address review comments

* use castStringKeyedMap

* introduce {bool,string,strings}Arg

* fix ci

Use PRODUCT_BUNDLE_IDENTIFIER from buildSettings to find correct bundle id on iOS when using flavors (#42964)

So we can test SkSL precompile using the command line tools.

## Description

Instead of detaching from the spawned App process on the device immediately, keep the LLDB client connection open (in autopilot mode) until the App quits or the server connection is lost.

This replicates the behavior of Xcode, which also keeps a debugger attached to the App after launching it.

## Tests

This change will be covered by all running benchmarks (which are launched via "flutter run"/"flutter drive"), and probably be covered by all tests as well.

I also tested the workflow locally -- including cases where the App or Flutter CLI is terminated first.

## Breaking Change

I don't believe this should introduce any breaking changes. The LLDB client automatically exits when the app dies or the device is disconnected, so there shouldn't even be any user-visible changes to the behavior of the tool (besides the output of "-v").

This updates the flutter tool cache to download binary files for ideviceinstaller, ios-deploy, libimobiledevice, and dynamically linked dependencies from Flutter's GCP bucket.
