[board] Fix some bugs in the starting position

Turns out I was doing the starting position really wrong. In an upcoming commit,
I will implement FEN output for Positions. While doing that work, I found several
issues that were causing the output of the FEN formatter to return garbage.
Implement a handful of unit tests to track down the errors.
Rename Shape::_ascii_representation() → Shape::to_ascii.
Implement to_ascii() on Piece.

[board] Add a test for capturing en passant; fix the bugs
...
I wrote a test for capturing en passant that revealed some bugs. Cool!
Implement the missing part of move validation that checks for an en passant move.
Implement PositionBuilder::to_move() to set player_to_move.
The most difficult part of this fix was finding the logic error in
Move::is_en_passant(). Instead of checking for non-zero, check for equality against
the en passant flag value. Checking for non-zero was causing this method to return
true in the double push case.

[board] Implement a PositionBuilder; refactor piece bitboards into a PieceBitBoards struct
...
This makes Position immutable, even if declared mut. I think this will also make
it easier to build positions going forward.
Moving to a PieceBitBoards struct also required a lot of places that return owned
BitBoards to return refs. This is basically fine except for adding a few more &
here and there.
This was a huge refactoring project. All the move generators and a bunch of
BitBoard stuff needed to be updated.
