Matter: list Window Covering commands in AcceptedCommandList (#25149)

The Shutter and Shutter + Tilt plugins handle UpOrOpen, DownOrClose,
StopMotion and GoToLiftPercentage (and GoToTiltPercentage for tilt) in
invoke_request(), but AcceptedCommandList (0xFFF9) of the Window
Covering cluster was empty. Controllers that build their feature set
from this list, such as Home Assistant, then don't offer setting the
position or tilt.

Override get_accepted_commands() in both plugins to report the
commands they implement.

Fixes #25146
