Keep all_frozen updated in heap_page_prune_and_freeze

Previously, we relied on all_visible and all_frozen being used together
to ensure that all_frozen was correct, but it is better to keep both
fields updated.

Future changes will separate their usage, so we should not depend on
all_visible for the validity of all_frozen.
