Provide and Configure DYNAMIC_PREEMPT
Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2019472
Tested: Kernels with the new options where tested for performance
by the perf QE team, see info in the bz. I confirmed generated
configs match expectations and sanity tested with scheduler stress
tests.
Provide CONFIG support for enabling DYNAMIC_PREEMPT on supported
architectures.
