Description of the new feature/enhancement

Hey, I was hoping for a feature in Windows Terminal that I've seen in many browsers and text editors: being able to close all tabs to the right of the current one. Here are some examples:

Sublime:

Firefox:

Chrome:

ConEmu:

The scenario I have is that I keep long-lived tabs like build processes, servers, etc. in the leftmost positions in my terminal, then I have "temporary" tabs on the right. Every once in a while, I end up with 20+ tabs open, so I want to activate the 6th or 7th one and close all tabs to the right to get rid of all of the clutter.

Even just having a customizable keyboard shortcut would be great, but this is the kind of thing that could live in a context menu eventually (#1912).

P.S. much of this text was copy/pasted from here.
