Resurrect WMFDecoderModule::HasAAC() and HasH264(), and use those in
MediaKeySystemAccess.cpp to figure out whether we gmp-clearkey can decode,
rather than assuming Vista and later is always able to decode, as that's not
a valid assumption; Vista may not have the required Platfor Update installed,
or we may be on Windows N or KN without the Media Feature Pack.

We're failing in the "Very rough kill-switch" case in
GMPVideoDecoderParent::Decode() we find that too many shmems are in use when we
come to send a "Decode" message to the GMP, and that causes an error which
percolates up to cause the test failure.
This patch changes gmp-clearkey to copy the input encrypted and compressed
sample and immediately return the shmem to the parent process. We are
copying the data anyway when we decrypt, so we can rejigg things so that we
don't actually end up doing a second copy.
