Move pawnsOnSquares to Position (#2100)

We can remove the values in Pawns if we just use the piece arrays in Position. This reduces the size of a pawn entry. This simplification passed individually, and in concert with ps_passedcount100 (removes passedCount storage in pawns.).

This is a non-functional simplification.
