Title: Move drush from main homebrew to homebrew-php

* Moved drush from main homebrew to homebrew-php.

The drush formula now requires a build dependency on composer which is
located in homebrew-php.

* Drush HEAD build depends on composer.

The HEAD version of drush has a build dependency on composer.

See Homebrew/homebrew#31696 and Homebrew/homebrew#30596 for issues regarding not having the formula in the main Homebrew repository anymore.
