  [Cocoa] Adopt AVSampleBufferAttachContentKey
https://bugs.webkit.org/show_bug.cgi?id=266289
rdar://115664955

Reviewed by Jer Noble.

Adopted AVSampleBufferAttachContentKey as a replacement to adding AVSampleBufferDisplayLayer and
AVSampleBufferAudioRenderer as content key recipients to an AVContentKeySession. This involves
finding the first content key that matches a sample's key by keyID, then attaching the key to the
sample prior to enqueueing it.

On macOS, this API requires the com.apple.private.coremedia.allow-fps-attachment entitlement; on iOS
it is enabled by an existing entitlement.

No new tests; covered by existing tests.
