Summary: Treat decimal literals as Double when
planner.enable_decimal_data_type is off (was: Treat decimal literals as Double
when type inference is taking place)

>
> In SQL standard, decimal literals (e.g., 1.2, 2.5, etc) are decimal types.
> However, currently, Drill always converts them to Double in DrillOptiq.
> Since they will be converted as Double in execution anyway, at inference, we
> can treat them as Double to help determine the return types.
> (The current behavior is "not to do any inference if the operand is Decimal
> type").
