Kernel: Rework Process::Priority into ThreadPriority

Browse source 
Scheduling priority is now set at the thread level instead of at the
process level.

This is a step towards allowing processes to set different priorities
for threads. There's no userspace API for that yet, since only the main
thread's priority is affected by sched_setparam().
