avcodec/libx264: bump minimum required version to 155
...
This version is seven years old, and present in Debian oldoldstable,
Ubuntu 20.04 and Leap 15.0.
Allows cleaning up the file substantially. In particular, this is
motivated by the desire to stop relying on init_static_data.

xHE-AAC relies on the same postfilter mechanism

The code to apply it is identical, it's still just a
simple IIR low-pass filter. This commit makes it possible
to use alternative constants.

AV1 supports encoding 8-bit content as 10-bit.
