Moves provider packages scripts to dev (#12082)

The change #10806 made airflow works with implicit packages
when "airflow" got imported. This is a good change, however
it has some unforeseen consequences. The 'provider_packages'
script copy all the providers code for backports in order
to refactor them to the empty "airflow" directory in
provider_packages folder. The #10806 change turned that
empty folder in 'airflow' package because it was in the
same directory as the provider_packages scripts.

Moving the scripts to dev solves this problem.
