avfilter: add VA-API variants of the stack filters

Include hstack_vaapi, vstack_vaapi and xstack_vaapi. They may accept input streams with different sizes. libva2 (VA-API 1.0+) is required. Example: $ ffmpeg -hwaccel vaapi -hwaccel_output_format vaapi -i input.h265 -filter_complex "[0:v][0:v]hstack_vaapi" -c:v h264_vaapi out.h264 $ ffmpeg \ -hwaccel vaapi -hwaccel_output_format vaapi -i input.h264 \ -hwaccel vaapi -hwaccel_output_format vaapi -i input.h264 \ -hwaccel vaapi -hwaccel_output_format vaapi -i input.h264 \ -hwaccel vaapi -hwaccel_output_format vaapi -i input.h264 \ -filter_complex "[0:v][1:v][2:v][3:v]xstack_vaapi=inputs=4:fill=0x000000:layout=0_0_1920x1080|w0_0_1920x1080|0_h0_1920x1080|w0_h0_1920x1080" \ -c:v hevc_vaapi out.h265
