2f77ecc6bc avcodec/riscv: add h264 qpel 
Benched on K230 for VLEN 128, SpaceMIT for VLEN 256. Variants for 4
width have no speedup for VLEN 256 vs VLEN 128 on available hardware,
so were disabled.

616fdeaea3 lavc/riscv: depend on RVB and simplify accordingly 
There is no known (real) hardware with V and without the complete B
extension. B was indeed required in the RISC-V application profile from
2022, earlier than V. There should not be any relevant hardware in the
future either.

In practice, different R-V Vector optimisations in FFmpeg already depend on
every constituent of the B extension anyhow, so it would not work well.

Unlike the 8-bit version, we need two iterations to process this within
128-bit vectors. This adds some extra complexity for pointer arithmetic
and counting down which is unnecessary in the 8-bit variant.

Accordingly the gain relative to C are just slight better than half as
good with 128-bit vectors as with 256-bit ones.
