debian/libva-v4l2-request-fourier: new package

Mirror of arch/libva-v4l2-request-fourier into the Debian tree. Same pin (de27e95), same build (meson + ninja), output as arm64 .deb installing the VA-API ICD as /usr/lib/aarch64-linux-gnu/dri/v4l2_request_drv_video.so. Auto-detected by VAAPI consumers (ffmpeg -hwaccel vaapi, mpv --hwdec=vaapi, Firefox VAAPI accel) when LIBVA_DRIVER_NAME=v4l2_request is set. build-deb.sh follows the lmcp pattern: reproducible build with SOURCE_DATE_EPOCH pin; standalone dpkg-deb so it runs on a non-Debian builder without dh/debhelper.

+Description: VA-API backend for V4L2 stateless decoders (fourier fork)
+ LibVA implementation for the Linux Video4Linux2 Request API, multiplanar
+ fork of bootlin/libva-v4l2-request.  Drives rkvdec / hantro / cedrus /
+ rpi-hevc-dec / daedalus_v4l2 stateless decoders for H.264, HEVC, VP8,
+ VP9, AV1, and MPEG-2.
+ .
+ Auto-detected by VAAPI consumers (ffmpeg -hwaccel vaapi, mpv --hwdec=vaapi,
+ Firefox VAAPI accel) when LIBVA_DRIVER_NAME=v4l2_request is set.
