py/gc: Add "max new split" value in result of gc.mem_free().
Follow-up to 519c24dd487 when MICROPY_GC_SPLIT_HEAP_AUTO is enabled, based
on discussion at
https://github.com/orgs/micropython/discussions/12316#discussioncomment-6858007
gc.mem_free() is always a heuristic, but this makes it a more useful
heuristic for common use cases.
