closes #1479

Description:

I already opened an issue and now had time to dig into the code.
When a user has reduced motion settings enabled in their system preferences, the player should respect this setting and not autoplay videos, regardless of the autoplay attribute value. This aligns with accessibility best practices and user preferences for reduced motion.

As a dev we could handle this with a simple check as @ianmiller347 already mentioned in the issue for example. But i think it would be a good practice to implement this directly so it works out of the box.

If the user prefers reduced motion and its autoplaying we throw during the play and not attemptAutoplay method because the auto-play-failed event is triggered by the play-fail event. Maybe i overlooked something and this could be improved.

Ready?
