Fixes: https://github.com/flutter/flutter/issues/60008

Remove global variables from device manager, flutter tester devices and update tests

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.

Now that google3 has been updated, remove the LICENSE loading fallback. This was done in cl/320506032

#16723

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.

* Normalize Pashto incomplete translations

* Add comment to README.md about incomplete Pashto support
