sched/core: Move, sort and clean up <linux/sched.h> structure predeclarations

Browse Source 
Most of the structure predeclarations were at the head of sched.h, but not
all of them - there were a number of lines spread around sched.h, in
random places.

Move them to the head, and also sort them alphabetically.

Remove unused entries.
