[Redesign] Remove AphrontTable restriction on Search Engine

Summary: Ref T8099, functionally I prefer to be able to set anything 'table-like' with setTable for design consistency. This looses the restriction and did some light grepping for other missed cases.

Test Plan: Test new UI, grep for other missing cases.
