visible
Calculates a bitboard of all squares "visible" or attacked by a specific piece from a given square.
Note on Pawn Behavior: For Piece.WP and Piece.BP, this returns only the squares targeted for capture (the diagonals). It does not include forward movement squares, as those are not considered "attacks" or "visible" interactions with other pieces.
Return
A Long bitboard representing all squares attacked or reachable by the piece.
