Capture player by reference in comestible inventory lambdas (#26272)

The lambdas for determining calories and joy for the player in the
comestible menu were capturing a copy of the player. With the
current map memory bugs, this meant a potentially very large object was
being copied several times, every time the comestible menu was
displayed, leading to a large delay.
