The pawn move generator only generated pushes for white pawns.

MoveSet needed a couple more validation methods: can_move_to_square and can_castle.
The MakeMoveBuilder also needed a little more move validation using the above methods.

[position] Calculate legal moves based on whether the king is in check
...
Use CheckingPieces to determine which and how many pieces check the king.
- If there are no checks, proceed with move generation as normal.
- If there is one checking piece, calculate push and capture masks and use those
to generate legal moves.
- If there are more than one checking pieces, the only legal moves are king
moves. Indicate this by setting the push and capture masks to EMPTY.
