Explicitly check for supported VCS
Summary: Instead of having an `ArcanistWorkflow` subclass explicitly throw an exception when run in an unsupported VCS, consolidate this code and move it to `arcanist.php`. In doing so, we lose some specificity in some of the error messages, but this otherwise feels cleaner. We could consider adding a `getUnsupportedRevisionControlSystemMessage()` method to provide a more tailored error message. Depends on D11604. Test Plan: Ran `arc bookmark` in a `git` working copy: ``` Usage Exception: `arc bookmark` is only supported under hg. ``` Reviewers: #blessed_reviewers, epriestley Reviewed By: #blessed_reviewers, epriestley Subscribers: Korvin, epriestley Differential Revision: https://secure.phabricator.com/D11550
