Support ordering in SearchField

Summary:
Ref T8441. Ref T7715. Automatically generate a modern "Order" control in ApplicationSearch for engines which fully support SearchField.

Notably, this allows the standard "Order" control to automatically support custom field orders. We do this in Maniphest today, but in an ad-hoc way.

Test Plan: Performed order-by queries in Almanac (Services), Pholio, Files, People, Projects, and Paste.
