  [Cocoa] Define a protocol to abstract FairPlay content key grouping
https://bugs.webkit.org/show_bug.cgi?id=261487
rdar://115396531

Reviewed by Eric Carlson.

In preparation for a new implementation of FairPlay content key grouping, define a protocol that
covers our use of AVContentKeyReportGroup SPI then extend AVContentKeyReportGroup to conform to the
protocol.

No new tests; no change in behavior.
