Now that GMPParent detects whether gmp-clearkey can decode using AAC/H.264 using WMF before reporting gmp-clearkey's GMPParent can decode AAC/H.264, we don't need the GMPDecryptorCallback::SetCapabilities() callback from the GMP to signal to the PDMFactory that the GMP can decode. We can now trust what the GMPService tells us. So we can remove the "waiting for CDM caps" step in the state machine's startup sequence. And all the plumbing. :) If we need more caps, like for an decode-and-render path, we can declare those as API strings in the info file.
