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 https://chromium-review.googlesource.com/c/chromium/src/+/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.
