avcodec/libx264: add support for writing out CLL and MDCV

Browse Source 
Both of these two structures were first available with X264_BUILD
163, so make relevant functionality conditional on the version
being at least such.

Keep handle_side_data available in all cases as this way X264_init
does not require additional version based conditions within it.

Finally, add a FATE test which verifies that pass-through of the
MDCV/CLL side data is working during encoding.
