Christian Schwarz 8c933a9686 page_cache: two-level immutable_page_map
This change alone makes things strictly worse, but on top of this, we'll
be able to rewrite drop_buffers_for_immutable to remove pages based on
what's in the `drop_file_id`'s immutable_page_map second-level hash map.
That's better than what we do currently, i.e., iterating over all the
slots.
