We separate the permission checks for content and topic edits
by changing the can_edit_topic_or_content to can_edit_topic
and use it only for checking topic edits and check content
edits separately in check_update_message itself. There is no
change in behavior as of this PR, there will be more changes
as per #21739.
This is a prep commit for #21739. The permission checks for
them are essentially separate except the one that message
sender is allowed to edit content and topic irresepctive of
edit_topic_policy setting, and this will too be changed in
future commit and so it will be better to have these checks
separate for readability.
We can also probably create a new function for checking content
edits but currently we only check the sender is same as the use
who is editing and it does not make sense to have a separate
function for just one check. We can do so in future in case we
do some more refactoring for #21739.
When there is no topic/stream being change, `propagate_mode` becomes
unnecessary. We add an assertion to ensure that the previous assumption
that `propagate_mode` is not `None` still holds when either `topic_name`
or `new_stream` is not `None`.
We can possibly improve this by overloading `do_update_message` and
`check_update_message`, but that's beyond the scope of the PR and
feasibility of doing that should also be further discussed.

When editing an old message in a private stream with protected
history, the server would incorrectly send an API event including the
edited message to all of the stream’s current subscribers, including
those who should not have access to the old message. This API event is
ignored by official clients, so it could only be observed by a user
using a modified client or their browser’s developer tools.

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`.
