Add Start with Tile View toggle to Conference Settings

It seems the default has changed to Tile View recently and I have to exit tile view every time I connect to my instructor led dance class. It would be nice to have a setting so a user can choose their default view in Jitsi. To be consist with the Start with audio muted toggle and Start with video muted toggle that already exists, maybe add a Start with tile view toggle. This would provide more flexibility so there is not one default for everyone. Hope this helps.
