media: v4l2-core: Add helpers to build the H264 P/B0/B1 reflists
Building those list is a standard procedure described in section '8.2.4 Decoding process for reference picture lists construction' of the H264 specification. We already have 2 drivers needing the same logic (hantro and rkvdec) and I suspect we will soon have more. Let's provide generic helpers to create those lists.
