Consolidate all attacks bitboards This is a non-functional simplification that simplifies getting attacks bitboards. * consolidates all attacks to attacks_bb (remove Position::attacks_from(..)). * attacks_bb<PieceType>(square) gets pseudo attacks * attacks_bb<PieceType>(square, bitboard) gets attacks considering occupied squares in the bitboard). * pawn_attacks_bb(Color, Square) gets pawn attacks like other pawn attack bitboards. * Wraps all access to PawnAttacks arrays and PseudoAttacks arrays and adds asserts as appropriate.
