sched/vtime: Get rid of generic vtime_task_switch() implementation
The generic vtime_task_switch() implementation gets built only
if __ARCH_HAS_VTIME_TASK_SWITCH is not defined, but requires an
architecture to implement arch_vtime_task_switch() callback at
the same time, which is confusing.
Further, arch_vtime_task_switch() is implemented for 32-bit PowerPC
architecture only and vtime_task_switch() generic variant is rather
superfluous.
Simplify the whole vtime_task_switch() wiring by moving the existing
generic implementation to PowerPC.
