Add a method to media::VideoDecodeAccelerator to indicate whether
SharedImage-backed picture buffers are supported. Make this return
true only for the VTVideoDecodeAccelerator.

Add a parameter to media::PictureBufferManager::CreatePictureBuffers
to indicate if SharedImage-backed PictureBuffers are desired.

Hook the two of these together in the ProvidePictureBuffersAsync
method of media::VdaVideoDecoder. Leave this disabled for now.
