-----------
[EME] getSupportedCapabilitiesForAudioVideoType can accidentally include
unsupported capabilities
https://bugs.webkit.org/show_bug.cgi?id=315667
Reviewed by Philippe Normand.
A local copy of accumulatedConfiguration is created where we append the
requestedCapability, then supportsConfigurationWithRestrictions is
queried. This means that requestedCapabilities cannot be accidentally
added when they aren't supported.
Tested on HBO Max, which was incorrectly serving HEVC content on a system
that didn't support it, and added a new test verifying this behaviour
after extending the MockCDMFactory to support this.
