Add a way to easily switch Accounts on mobile

I love how little you need to do to switch accounts on desktop, but I don't like the fact that the same thing isn't implemented on discord mobile.

maybe a button under the profile (not settings) that lets you easily switch accounts like you can in desktop by clicking status which is pfp and a short display of the status, click switch accounts and choose which one to switch to.

and ability to sync switchable accounts between devices
