cpuset: add cpuset1_online_css helper for v1-specific operations

Browse source

This commit introduces the cpuset1_online_css helper to centralize
v1-specific handling during cpuset online. It performs operations such as
updating the CS_SPREAD_PAGE, CS_SPREAD_SLAB, and CGRP_CPUSET_CLONE_CHILDREN
flags, which are unique to the cpuset v1 control group interface.

The helper is now placed in cpuset-v1.c to maintain clear separation
between v1 and v2 logic.
