mm/slub: unify slub stat definitions to simplify metric additions
Currently, adding a new slub stat requires modifying three separate
locations: stat_item, STAT_ATTR, and slab_attrs. This is inconvenient,
especially when temporarily adding metrics for debugging during
development.
This patch borrows the approach from SCHED_FEAT by introducing an ITEM_EXP
X-macro, which is then temporarily defined as different operations at the
three locations (stat_item, STAT_ATTR, and slab_attrs) to perform distinct
macro expansions.
Going forward, adding a new metric only requires adding a single line:
ITEM_EXP(XXX, xxx)
