sched/topology: Move SD_DEGENERATE_GROUPS_MASK out of linux/sched/topology.h

SD_DEGENERATE_GROUPS_MASK is only useful for sched/topology.c, but still
gets defined for anyone who imports topology.h, leading to a flurry of
unused variable warnings.

Move it out of the header and place it next to the SD degeneration
functions in sched/topology.c.
