Andrea Righi 0aaaf89df8 sched_ext: idle: Introduce SCX_OPS_BUILTIN_IDLE_PER_NODE ...

Add the new scheduler flag SCX_OPS_BUILTIN_IDLE_PER_NODE, which allows
BPF schedulers to select between using a global flat idle cpumask or
multiple per-node cpumasks.

This only introduces the flag and the mechanism to enable/disable this
feature without affecting any scheduling behavior.
