Add a UserProfileScreen for profiles of non-members.

[pixlwave]

The PR is the first part of #2634. It makes the following changes:

• Adds a UserProfileScreen which is a cut down version of the RoomMemberDetailsScreen.
• Replaces the member details screen in the stack with the user profile screen when the user can't be found in the room.

Still required to close the task:

• Handle external links with a different route and present the user profile screen directly in the user session flow.
