What problem does this PR solve?

If the cache capacity adjustment is not completed within 500ms (conf::memory_gc_sleep_time_ms), the next adjustment will be skipped.

In some scenarios, after Memory GC adjusts the cache capacity to 0, the next adjustment to restore the cache capacity is skipped, the cache capacity will remain at 0 for a long time.
