We should not monkey-patch message when unnecessary. Adding
`service_queue_events` to `SendMessageRequests` suits our need to type
safety here.

Now that we can assume Python 3.6+, we can use the
email.headerregistry module to replace hacky manual email address
parsing.

The type safety of a TypeGuard is unchecked by mypy. While this
particular TypeGuard is safe given the current context, one could
imagine future changes that make it unsafe, so it’s preferable to
avoid unchecked constructs whenever possible.

django-stubs types the return type of query.values(...) as a TypedDict.
This makes Dict[str, Any] that we have been using incompatible with it.
We use TypeGuard to ensure that `service_bot_tuples` is correctly
inferred to be `Tuple[int, int]` instead of `Tuple[int, Optional[int]]`.
Given that `bot_type` is optional for `ActiveUserDict`, we need to
narrow `row` to `ActiveBotUserDict` to make sure that `bot_type` is
non-optional. An advantage of this approach is that no assertions or
type casts are needed.

To explain the rationale of this change, for example, there is
`get_user_activity_summary` which accepts either a `Collection[UserActivity]`,
where `QuerySet[T]` is not strictly `Sequence[T]` because its slicing behavior
is different from the `Protocol`, making `Collection` necessary.
Similarily, we should have `Iterable[T]` instead of `List[T]` so that
`QuerySet[T]` will also be an acceptable subtype, or `Sequence[T]` when we
also expect it to be indexed.

cfcbf58cd1 rightly removed the use of `user_ids` in
`render_markdown`, which in turn makes it unnecessary in
`render_incoming_message`.
Remove the unnecessary parameter from `render_incoming_message`.
The `get_link_embed_data` / `link_embed_data_from_cache` pair as
introduced in c93f1d4eda uses the cache
as a temporary store inside of the `embed_links` worker; this means
that it must be durable storage, or the worker will stall and re-fetch
the same links to preview them.
Switch to plumbing through the fetched URL embed data as an parameter
to the Markdown evaluation which uses them, rather than using the
cache as an intermediary. This frees up the cache to be merely a
non-durable cache.
As a side-effect, this removes get_cache_with_key, and
link_embed_data_from_cache which was its only callsite.
