Summary:
Depends on D18862. See PHI173. Ref T13025. Fixes T10005. This redefines bulk edits in terms of EditEngine fields, rather than hard-coding the whole thing.
Only text fields -- and, specifically, only the "Title" field -- are supported after this change. Followup changes will add more bulk edit parameter types and broader field support.
However, the title field now works without any Maniphest-specific code, outside of the small amount of binding code in the `ManiphestBulkEditor` subclass.
Test Plan: Used the bulk edit workflow to change the titles of tasks.
