Consider adding new scalar comparison primitives for Datetime and Ordinal column types

[thehomebrewnerd]

In PR #2434 Datetime and Ordinal inputs were removed from the valid input types for four comparison primitives. This was done due to errors that could be encountered during feature value calculation. We should consider adding new primitives to replace the lost functionality, if these types of comparisons are needed.

The Ordinal comparison primitives might be too specific and may not be necessary, but the datetime comparison primitives could be useful.

Some primitives to add could include (naming could be improved):
GreaterThanDate
GreaterThanOrEqualToDate
LessThanDate
LessThanOrEqualToDate
