Bug 1917721 - Make AAC-w/o-description WPT a mozilla-specific WPT r=m…

…edia-playback-reviewers,padenot

Due to the ongoing discussion in issue 832 [1], which has not yet
reached a consensus among all parties, the AAC-without-description WPT
introduced in the previous patch should be relocated to the *mozilla*
folder under WPT. This ensures that the test remains specific to Mozilla
and avoids unintentionally causing failures in other browers' test
suites.
