On Wayland, the task thumbnail takes some time to load. After it's loaded, the thumbnail will suddenly appear without any animation, which makes the visual experience unpleasant.

2. Enable "Show tooltips" and Open many windows
3. Hover on the grouped task

OBSERVED RESULT
Unpleasant visual experience

EXPECTED RESULT
Some transitions can be performed after the thumbnail is loaded.

libtaskmanager: Set enabled according to visible property

`enabled` must be set in the backend because `visible` will always be
true after getting a valid nodeId, and sometimes we need to reset `enabled`
to false.

taskmanager: Load "PipeWireThumbnail.qml" asynchronously

So thumbnails in grouped task tooltips can be shown almost at the same
time.
