Bug 1872973 - part1 : use default config for clearkey. r=jolin

Browse Source 
For the media fundation based CDMs, we usually use WMFCDMImpl to get a
capabilities from the MFCDM process in order to get a precise
capabilites result from CDMs.

However, for clearkey, it's all implemented by ourselves and its
capabilites always keep the same, so we can simply just use our
predefined capabilites without asking the MFCDM process.
