vulkan_ffv1: cache only 2 lines when decoding RGB

Browse Source 
This reduces the intermediate VRAM used for RGB decoding by a
factor of 100x for 6k video.
This also speeds the decoder up by 16% for 4k RGB24 and 31% for 6k video.

This is equivalent to what the software decoder does, but with less pointers.
