Add pipewire/portal video capture support

This makes it possible to access cameras through xdg-desktop-portal and
pipewire.

For pipewire, a shared state is needed between the enumeration and the
creation of camera object. So a new API is needed with a shared options
object that holds the state and can be used to choose which backend to try.
