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.
