Limit netplay chat messages to 2000 characters.

There's not really a good reason to be sending messages longer than that, and very long messages can hang dolphin for quite a long time.

This does what it says so I'm fine with this, but I do have a suggestion which can add on to this.

I'm not sure how the Netplay UI looks in terms of how the chatting is handled (never used netplay), but possibly a limit notifier can be added in some form. One that's like 0/2000 that counts up from the left-hand side and disallows adding more characters to the message once that limit is hit (ie. 2000/2000). Don't let this be a PR blocker though.

Hmm, i don't think there's really any good place to put that in the ui. Limiting the text box is probably a good idea though.

Since the text box is capped at 2000 characters now, is the other check still necessary?

@lioncash never trust network input :)
