[3.14] gh-142531: Fix free-threaded GC performance regression (gh-142562) (gh-142617) 
If there are many untracked tuples, the GC will run too often, resulting
in poor performance.  The fix is to include untracked tuples in the
"long lived" object count. The number of frozen objects is also now
included since the free-threaded GC must scan those too.
(cherry picked from commit e38967ed60778146050cc88dd16b70bfd867fde7)
