SQL: Improve translation of time floor expressions. (#5107) 

* SQL: Improve translation of time floor expressions.

The main change is to TimeFloorOperatorConversion.applyTimestampFloor.

- Prefer timestamp_floor expressions to timeFormat extractionFns, to
  avoid turning things into strings when it isn't necessary.
- Collapse CAST(FLOOR(X TO Y) AS DATE) to FLOOR(X TO Y) if appropriate.

* Fix tests.
