omegaga e70020e4f6 Only cache level 0 indexes and filter when opening table reader ... Summary: In T8216281 we decided to disable prefetching the index and filter during opening table handlers during startup (max_open_files = -1). Test Plan: Rely on `IndexAndFilterBlocksOfNewTableAddedToCache` to guarantee L0 indexes and filters are still cached and change `PinL0IndexAndFilterBlocksTest` to make sure other levels are not cached (maybe add one more test to test we don't cache other levels?)
