Reuse Promotion Type Natively
Piece promotion is generated, and then type_of(promotion) is used to retrieve
the underlying type. The class Move provides .promotion_type() natively,
meaning we can cache the type directly and avoid extracting it indirectly
afterward. By extracting pt = m.promotion_type(); up front, we don't need to
call type_of(promotion) iteratively inside the assertions or conditions below.
