[Mobile] Have read all option for inbox

[Ashley719161718]

I mostly use canvas on my iPhone and there are zero features on the app for reading all unread messages in the inbox, so I’m left with a huge amount of unread messages on my phone. The only way to read them is to click and close each individual one which is tedious when your professors upload zoom recordings to the course multiple times a week.
