Pokemon RB: make stage_post_fill deterministic (#4008) 

stage_post_fill iterates sets of locations, so the iteration order is
non-deterministic, resulting in different items being converted from
Progression to Useful when generating with the same seed.

This patch makes stage_post_fill deterministic by sorting the duplicate
pokemon locations in each sphere before choosing which of the duplicates
should remain as progression.
