According to the driver's instruction, if there are two or more encoders or decoders in a process, the session should be joined by MFXJoinSession. To achieve this successfully by GstContext, this patch adds job type specified if it's encoder, decoder or vpp. If a msdk element gets to know if joining session is needed by the shared context, it should create another instance of GstContext with joined session, which is not shared. https://bugzilla.gnome.org/show_bug.cgi?id=790752
