In a scenario where a bank is unrooted and dropped, any keys that exist
_only_ in that bank are now cleaned up.
This work was originally based on PR #15106.

While working on another issue (#16580), the list of uncleaned pubkeys
returned from `remove_uncleaned_slots_and_collect_pubkeys_up_to_slot()`
did not include unrooted slots. This meant that during cleaning,
unrooted slots would not have their pubkeys cleaned up properly.
Now, return all uncleaned pubkeys, regardless if the slot is rooted or
not. Additionally, update the tests to have unrooted slots to ensure
this behavior.
This is part two of PR #16879, and originally based on PR #15106.
* Refactor `collect_uncleaned_pubkeys_to_slot()`
While working on another issue (#16580), I came across
`collect_unclean_pubkeys_to_slot()` and had difficulty understanding it.
Since the function does a few logically separate things, I split the
function up. I also added documentation, removed an unused return value,
and renamed the functions to be more specific.
This commit is to split up an existing PR (#16786), where I had both this
aesthetic change _and_ a behavioral change.
