sched: convert cpu_isolated_map to cpumask_var_t.

Impact: stack usage reduction, (future) size reduction, cleanup

Dynamically allocating cpumasks (when CONFIG_CPUMASK_OFFSTACK) saves
space for small nr_cpu_ids but big CONFIG_NR_CPUS.  cpumask_var_t
is just a struct cpumask for !CONFIG_CPUMASK_OFFSTACK.

We can also use cpulist_parse() instead of doing it manually in
isolated_cpu_setup.
