[Cocoa] EME with encrypted MPEG2-TS fails to begin playback
https://bugs.webkit.org/show_bug.cgi?id=268948
rdar://122030589

Reviewed by Andy Estes.

When encrypted samples are parsed from containers by AVStreamDataParser, those samples have
their associated initialization data attached to their CMFormatDescription as extensions.
WebKit then reads those initialization data from the format description to determine the
keyID needed to decrypt that key. For MPEG2-TS files, the initialization data is stored
in a different key/value pair. Explicitly support this initData type as 'mpts'.

Looks like failing tests will require bot upgrades to newer platform OSs. Will skip for now.
