I'd make the title something like "libavfilter: add rotate_vaapi filter".
There is no reason to mention a particular implementation - anyone can
implement this API.

It supports clockwise rotation by 0/90/180/270 degrees defined in
va/va_vpp.h, tested following command line on SKL platform
ffmpeg -hwaccel vaapi -vaapi_device /dev/dri/renderD128
-hwaccel_output_format vaapi -i input.264 -vf "rotation_vaapi=angle=180"
-c:v h264_vaapi output.h264
