[spice v1 2/2] display-channel: Make video-codecs readwrite

[Victor Toso <victortoso@xxxxxxxxxx>]

From: Victor Toso <me@xxxxxxxxxxxxxx>

By making video-codecs readeable, we can avoid other objects to access
the internals of DisplayChannel.

The GArray video-codecs is copied as static, no need to unref it
afterwards.
