Add option to find own location in map views

[Johennes]

This exposes the default "find my location" button in the map view dialog for static and live locations. When the user is currently live-sharing their own location, the button is hidden.

Todo

I couldn't find a suitable existing icon for this so I reused one of the map marker icons for demonstration purposes. We'll probably need to make a new one.

It also currently only centers the map on the user location when clicking for the first time.

I'm not sure I understand the need of adding a button here as zoom in and finding user location should be automatic when opening the map. Also this is the space dedicated to the Sharing option why are you replacing it?

Thanks for getting back @gaelledel.

This is for the case when the user is not sharing their own location but instead viewing somebody else's location share.

Also this is the space dedicated to the Sharing option why are you replacing it?

The screenshot is from the live location map view. That one currently doesn't have the share button. You are right though that for static location shares, the map view would have to show both, the share button and the "find my location" button.
