radeon: Add cropping to encoded H.265 when padding is used

Browse source 
Because the VCN encoder needs the surface to be memory aligned, the
resolution of the image passed to the encoder might be larger and have
extra padding added - this change crops the resulting output to
compensate for the extra padding that might have been added.
