When all entries in an `LruCache` have a size of 0 according to the
provided `size_callback`, and `drop_from_cache` is called on a cache
node, the node would be unlinked from the LRU linked list but remain in
the cache dictionary. An assertion would be later be tripped due to the
inconsistency.
Avoid unintentionally calling `__len__` and use a strict `is None`
check instead when unwrapping the weak reference.
Part of https://github.com/matrix-org/synapse/issues/11300
Call stack:
- `_persist_events_and_state_updates` (added `use_negative_stream_ordering`)
- `_persist_events_txn`
- `_update_room_depths_txn` (added `update_room_forward_stream_ordering`)
- `_update_metadata_tables_txn`
- `_store_room_members_txn` (added `inhibit_local_membership_updates`)
Using keyword-only arguments (`*`) to reduce the mistakes from `backfilled` being left as a positional argument somewhere and being interpreted wrong by our new arguments.
Since e81fa92648, Synapse depends on
the use_float flag which has been introduced in ijson 3.1 and
is not available in 3.0. This is known to cause runtime errors
with send_join.

The previous fix for the ongoing event fetches counter
(8eec25a1d9) was both insufficient and
incorrect.
When the database is unreachable, `_do_fetch` never gets run and so
`_event_fetch_ongoing` is never decremented.
The previous fix also moved the `_event_fetch_ongoing` decrement outside
of the `_event_fetch_lock` which allowed race conditions to corrupt the
counter.
This change makes mypy complain if the constants are ever reassigned,
and, more usefully, makes mypy type them as `Literal`s instead of `str`s,
allowing code of the following form to pass mypy:
```py
def do_something(membership: Literal["join", "leave"], ...): ...
do_something(Membership.JOIN, ...)
```
