  [EME] Video using protected audio fails to start playing after seek
https://bugs.webkit.org/show_bug.cgi?id=300581
rdar://162461088

Reviewed by Jer Noble.

SourceBufferPrivateAVFObjC::canEnqueueSample would have always returned false 
for
a protected audio sample. We revert to the behaviour prior 301011@main.

Fly-By: some comments were missed in the original review of 301011@main
which also had flagged the problem just fixed. Those were missed. Apply them 
now.

Added tests. They are disabled by default, will be handled in 
webkit.org/b/300597
