fix: ensure that requestMediaKeySystemAccess resolves (#34886)

Browse source 
When widevine was disabled at the build level we never dealt with the callback passed into GetSupportedKeySystems.  This was ok until requests became marked pending in 3430502 until the callback was called.  This resulted in a promise never resolving / rejecting and certain media websites (E.g. spotify) hanging on load waiting for a signal that would never arrive.
