gstreamer: Associate libcamera::Stream with GstPad

Browse Source 
Instead of trying to figure out which libcamera::Stream, the GstPad
is configured with (from the libcamera pool), associate the Stream
with the GstPad directly. The association can be set using
gst_pad_set_element_private().

Add the gst_libcamera_pad_set_stream() helper to associate the stream
with the pad. Additionally, modify the gst_libcamera_pad_get_stream()
to use to the getter helper gst_pad_get_element_private().
