A HTMLMediaElement created while page is interrupted should be able to autoplay
https://bugs.webkit.org/show_bug.cgi?id=241783

Patch by Youenn Fablet <youennf@gmail.com> on 2022-06-21
Reviewed by Eric Carlson.

Previously, a session created while manager is interrupted would get its state set to interrupted.
When end of interruption happens, it would not be restarted since its interruption count would be set to 0.
Instead, manager now stores the last interruption.
In case of a new session, we now call beginInterruption instead of setting the session state directly.
This allows to have an interruption count set to 1 and thus uninterrupt the session when the end of interruption signal happens.

Covered by added test.
