qtdemux: use GPtrArray for crypto_info to avoid GstStructure copies

By using a GPtrArray of GstCaps rather than a single GstCaps, the
gst_qtdemux_decorate_and_push_buffer() function can avoid having to do a copy
of the content protection related GstStructure for each sample. This reduces
the memory and CPU consumption of encrypted streams.
