sched: Move most HMP specific code to a separate file.
Most code pertaining to CONFIG_SCHED_HMP has been moved to a separate
file "hmp.c" in order to facilitate kernel upgrades. Fewer changes in
the original scheduler files means fewer conflicts. Some parts of code,
however, could not be moved to the separate file either because of
dependencies with other non-HMP code or because the changes are specific
only to the scheduling classes where the code resides.
