https://bugs.webkit.org/show_bug.cgi?id=251587

Reviewed by Philippe Normand.

Enable PlayReady if the Thunder plugins are present.

Also add a small check just in case there is no Thunder running in debug mode.

Added key ID corner case hack. Sometimes PlayReady key IDs come with some bytes swapped so we add both original and
swapped key IDs to the hashmap.
