Makes your current position clearer while jaunting (#90173)

## About The Pull Request

I was fucking around testing the Voidwalker earlier for a different
issue and didn't like that I couldn't see myself while in space.
This PR makes it so that Voidwalkers and also any variant of Ethereal
Jaunt place an icon visible only to you at your current position (it's
like your _soul_) so that you can see where you are going.
Nobody else can see it.

There are almost certainly some other sources of being invisible which
could use this so let me know if you are aware of one.
Although if you do that I may need to make my code more generic.

## Why It's Good For The Game

It's nice to be able to see where you are precisely rather than just it
being the centre of the screen
