sched/x86: Change CONFIG_SCHED_ITMT to CONFIG_SCHED_MC_PRIO
Rename CONFIG_SCHED_ITMT for Intel Turbo Boost Max Technology 3.0
to CONFIG_SCHED_MC_PRIO. This makes the configuration extensible
in future to other architectures that wish to similarly establish
CPU core priorities support in the scheduler.
The description in Kconfig is updated to reflect this change with
added details for better clarity. The configuration is explicitly
default-y, to enable the feature on CPUs that have this feature.
It has no effect on non-TBM3 CPUs.
