Make Arcanist workflow names explicit

Summary:
Currently, adding a new workflow requires you to override ArcanistConfiguration, which is messy. Instead, just load everything that extends ArcanistBaseWorkflow.

Remove all the rules tying workflow names to class names through arcane incantations.

This has a very small performance cost in that we need to load every Workflow class every time now, but we don't hit __init__ and such anymore and it was pretty negligible on my machine (98ms vs 104ms or something).

Test Plan: Ran "arc help", "arc which", "arc diff", etc.
