sched/isolation: Save boot defined domain flags
HK_TYPE_DOMAIN will soon integrate not only boot defined isolcpus= CPUs
but also cpuset isolated partitions.
Housekeeping still needs a way to record what was initially passed
to isolcpus= in order to keep these CPUs isolated after a cpuset
isolated partition is modified or destroyed while containing some of
them.
Create a new HK_TYPE_DOMAIN_BOOT to keep track of those.
