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.
