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

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

If an asset was included directly from the project root directory, then the same asset when copied to various output or ephemeral directories would also be picked up as an asset variant. This could cause assets to be recursively copied into asset/build/ephemeral directories, as each time it would run it would pick up all of the previous "variants".

The solution is to include project ephemeral directories, in addition to the build directory.
