Summary:
Ref T2015. Not directly related to Drydock, but I bumped into this. All these scripts currently enumerate their workflows explicitly.
Instead, use `PhutilSymbolLoader` to automatically discover workflows. This reduces code duplication and errors (see all the bad `extends` this diff fixes) and lets third parties add new workflows (not clearly valuable?).
Test Plan: Ran `bin/x help` for each modified script.

Summary: Fixes T3679. This comes up every so often and the old script is extremely broad (nuke everything in a repository). Provide a more surgical tool.
Test Plan: Ran a bunch of variations of the script and they all seemed to work OK.
