_0Steven 03fa31e5d2 Custom emotes actually use +|_ emphasis formatting, your own emotes don't trip highlights (#90858)
<!-- Write **BELOW** The Headers and **ABOVE** The comments else it may
not be viewable. -->
<!-- You can view Contributing.MD for a detailed description of the pull
request process. -->

So I was running into the bit where custom emotes actually don't get the
`+|_` emphasis formatting applied to them, _except_ for the runechat
portion which *does*.
This felt annoying, especially given I've seen a lot of people try it
and have it not work.
Add to that that your own emotes would keep getting highlighted,
blotting out other people mentioning your highlighted messages, and
here's this pr.

In this pr we add a few flags to audible/visible messages,
`WITH_EMPHASIS_MESSAGE` and `BLOCK_SELF_HIGHLIGHT_MESSAGE`, which
respectively apply emphasis formatting and block highlighting the
message to oneself.
We're doing this with flags because I felt always applying this would be
unnecessary. Most audible/visible messages won't need to check for
formatting, and quite a lot we *do* want to be highlighted.

As such, we apply these flags as need be.
For emotes we do this by having `get_message_flags(intentional)`, which
applies `BLOCK_SELF_HIGHLIGHT_MESSAGE` based on whether the message is
intentional, and on the custom emote subtype applies
`WITH_EMPHASIS_MESSAGE`.

Because it's not just for _say_ anymore, and already was also used for
emote runechats, we rename `say_emphasis(input)` into
`apply_message_emphasis(input)`. We additionally move it down to `/atom`
from `/atom/movable`, such that visible/audible messages can in fact
call it.

That resolves our issues.

We also apply `BLOCK_SELF_HIGHLIGHT_MESSAGE` to sign language tone
messages, as they're essentially a part of speech.

<!-- Describe The Pull Request. Please be sure every change is

Being able to do `+|_` emphasis formatting on your emotes is nice, I've
seen a lot of people try it and have it not work.
Especially weird given it DOES apply to the runechat message, just not
the text chat message.

It's annoying when your own emotes trip your own highlights! Like if you
have a name highlight, your own emotes getting constantly highlighted
would blot out other people talking to you.
So having your own emotes not trip it just like your own talking makes
that less of a pain.
But sometimes emotes are forced, and in that case I think it's better to
keep the highlight because it's just like other people's messages
information the player might want to be notified of.
Generally, I think if it's the player's input it probably shouldn't be
highlighted, while if it isn't the player's input it probably should.

There's no need for us to ever highlight our own sign language tone
messages, because they're essentially a part of our talking.

🆑
add: When performing a custom emote, `+|_` emphasis formatting applies
to the text chat message instead of just the runechat message.
qol: Intentional emotes don't trip your own highlights.
qol: Sign language tone messages don't trip your own highlights.
