Parser: adapt to the libvlc_parser split

Refs vlc!10169

Replace queue() and queueThumbnailing() with createParseTask(),
createThumbnailTask() and submit().

The create methods return a move-only Task object, which submit()
consumes on success. Submitting it twice or to another parser throws
to avoid undefined behavior. Task::id() returns a TaskIdentifier,
fetched before submission to identify it in callbacks, which now
exposes the same TaskIdentifier for that task.

Bump the libvlc wrap to 778ec071ff216602f2a6e4ddd522dfdb6b791472.
