docs: cgroup-v2: Describe boot-isolated CPUs in cpuset.cpus.isolated
cpuset.cpus.isolated is documented as empty when no isolated partition
exists. This is not true when CPUs are isolated at boot with
isolcpus=domain. cpuset_init() adds those CPUs to the isolated mask,
and isolcpus=<cpu-list> uses domain isolation by default. They remain
listed after a partition using them is released.
Document the boot-isolated CPUs as well.
