PyAPI: Expose event.type_prev, value_prev

Before [0] mouse-motion events left the 'event.value' un-changed,
so a mouse-move would be set to PRESS/RELEASE based on previous events.

Support accessing the previous event value directly
to address feedback from T99102.

Note that the previous cursor location is already exposed.
