Mind links won't highlight your own messages (#84625)

## About The Pull Request

Linked speech now prevents messages from highlighting if its a message
you sent, or if you are the owner of said link.

Also, linked speech messages are now marked as radio messages, for chat
tab purposes.

## Why It's Good For The Game

Because when you have your own name highlighted, it's annoying having
every message with `[Shion Rosenthal's Slime Link]` highlighted, even if
it's _my own_ message.

## Changelog
:cl:
qol: Linked speech now prevents messages from highlighting if its a
message you sent, or if you are the owner of said link..
qol: Linked speech messages are now marked as radio messages, for chat
tab purposes.
