[PATCH 1/2] channel-display-gst: Prefer playbin3 to playbin (v2)

[Vivek Kasireddy <vivek.kasireddy@xxxxxxxxx>]

From: Jin Chung Teng <jin.chung.teng@xxxxxxxxx>

If playbin3 is available (checked in Gstreamer registry), it
makes sense to prefer it given the major improvements and
features it offers including the capability to handle higher
bitrates.

v2: (Frediano)
- Cache the playbin3 is available check
- Keep the playbin name for playbin3 element as well
