remote-desktop: Check for screencast only when required

Browse Source 
The portal API requires a screencast session only for absolution motion
with remote desktop, other methods including relative motion do not
require a screencast session.

There is no reason to be more strict than the API actually is, check for
a screencast session only when required, like for absolute motion events
and touch events.

Tested with https://gitlab.gnome.org/snippets/1122

Closes: https://gitlab.gnome.org/GNOME/mutter/-/issues/1307
