sched: drop sched.h dependency on cpumask
sched.h needs cpumask.h mostly for types declaration. Now that we have
cpumask_types.h, which is a significantly smaller header, we can rely on
it.
The only exception is UP stub for set_cpus_allowed_ptr(). The function
needs to test bit #0 in a @new_mask, which can be trivially opencoded.
