Implement basic touch support

This required changing container_at_cursor to container_at_coords so
that we could get the appropriate surface (and sx/xy) without moving the
cursor.

Future work:

- Simulate a cursor for clients which have not bound to wl_touch
- Keep sending motion events when moving outside the surface (#1892)
- Bind gestures to sway commands
