encoder: avoid extra allocations of GstVaapiEncoderSyncPic objects.
Kill GstVaapiEncoderSyncPic objects that are internally and temporarily allocated. Rather, associate a GstVaapiEncPicture to a coded buffer through GstVaapiCodedBufferProxy user-data facility. Besides, use a GAsyncQueue to maintain a thread-safe queue object of coded buffers. Partial fix for the following report: https://bugzilla.gnome.org/show_bug.cgi?id=719530
