* Use `dart __deprecated_pub` instead of `pub` to invoke pub from tools

The top level `pub` commmand has been deprecated and will print
a message. It is however implemented via the __deprecated_pub command
that prints no message.

This reverts commit 53d8cba3.

[custom-devices] general improvements, add custom-devices subcommand, better error handling (#82043)

* opt out the flutter tool

* oops EOF

* fix import

* Update tool_backend.dart

* Update daemon_client.dart

* fix more

This reverts commit 388dcd24.

This reverts commit 1cb0a24a.

* [flutter_tools] Serve DevTools at app start

* Reorganize files

* Use l10n.yaml instead of command line args

* Launch DevTools from pub instead of devtools_server

initialize the flutter root as early as possible. This allows all interfaces to be normally injected into commands, even if those objects might read from the flutter root.

Overhaul of flutter drive in order to deliver a better experience, namely:

* flutter run and flutter drive now share more flags, so code paths that were previously only testable on run are now testable on drive.
* Removes web-initialize-platform as this is no longer used
* flutter drive correctly sets up a logger that shows native exceptions, by connecting to the vm service.
* VM service connection now provides access to memory info without launching devtools (only for debug/profile mode)

Web changes

* Passes on the one test in the repo, otherwise the webdriver code has been isolated as much as possible

Additional NNBD related bug fixes:

No longer passes --enable-experiment to the test script. (FYI @blasten ). earlier we might have assumed that the flutter gallery benchmarks would be migrated along side the app and flutter driver, but only the app under test needs to be migrated. The test scripts should never be run with the experiment.

Remove "This is taking a long time" progress timeout and TimeoutConfiguration.

The train command does nothing and was originally added to provide a no-output default for generating app-jit snapshots. The inject-plugins command is only for a repo-only analysis check, which is not necessary since we regenerate during pub get.

#29805

Re-arrange the implementation of the devtools launcher so that google3 is not required to depend on any devtools packages. Also renames the build_runner folders to isolated to better clarify their intention.

complete removal of all generate functionality

Fixes #61508

We have too many loggers, and the logger construction rules are too complicated to be untested. Capture these in a LoggerFactory and test that construction is correct.

Inject loggers in the right order, test WIP. Otherwise verbose machine would not get the AppRunLogger

Running flutter doctor -v prints out extra details instead of running in verbose mode. Allow disabling this with -vv so it can be debugged.

run/attach --machine requires a different logger than daemon, which uses the NotifyingLogger. We have too many loggers!

Fixes #59463

update flutter precache --force to delete all stamp files. In the event that a user is hitting a cache issue, this should be easier than re-downloading all artifacts or manually blowing away the cache.

This is probably how it should have worked in the first place

Refactors KernelCompiler and ResidentCompiler to no longer use globals (except as a fallback for g3 migration). Improves the compilation error when running flutter test on a package without a flutter_test dependency.

Updates machine mode to output trace text to stderr
