Add specific close status queries to maniphest.find (and rename it to maniphest.query)
Summary:
- Allow clients to query for specific closed statuses (invalid, resolved, wontfix, etc), not just "closed" tasks.
- Rename this method to maniphest.query and deprecate maniphest.find as an alias to maniphest.query, for API consistency.
Test Plan: Ran queries for all tasks, "wontfix" tasks, closed tasks.
