sched_ext: Wrap global DSQs in per-node structure

Browse source

Global DSQs are currently stored as an array of scx_dispatch_q pointers,
one per NUMA node. To allow adding more per-node data structures, wrap the
global DSQ in scx_sched_pnode and replace global_dsqs with pnode array.

NUMA-aware allocation is maintained. No functional changes.
