Delete the InsertionMarkerManager

[BeksOmega]

We should delete the InsertionMarkerManager and any remaining references to it. There may be some complications where it hooks into the renderer that mean we have to keep some enums.

Hey. Can you assign the issue to me please?

[BeksOmega]

Go for it @ChaitanyaYeole02 =) Let me know if you have any questions!

[BeksOmega]

Ah actually @ChaitanyaYeole02 I didn't realize this wasn't a good-first-issue when I assigned it. Might be better to start with something like #8342 instead =)

[ChaitanyaYeole02]

Ok sure, I will work on #8342 instead.

Hey @BeksOmega, I have done two good first issues. I am not able to find any more available right now. Do you think, that I could work on this right now?

[BeksOmega]

Sounds good! But like the issue warns, there might be some trickiness. Let me know if you have any questions =)
