sched/isolation: Split housekeeping cpumask per isolation features
Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2065222
Depends: https://bugzilla.redhat.com/show_bug.cgi?id=2065994
Tested: Setup isolation and ran scheduler tests, checked that housekeeping
looked right (tasks offloaded from isolated cpus to HK ones etc).
Split the housekeeping flags into finer granularity in preparation
for allowing them to be configured dynamically. There should not be
much functional change.
