[SPARK-8752][SQL] Add ExpectsInputTypes trait for defining expected input
types.
This patch doesn't actually introduce any code that uses the new
ExpectsInputTypes. It just adds the trait so others can use it. Also renamed
the old expectsInputTypes function to just inputTypes.
We should add implicit type casting also in the future.
