Add the definition for the generic line based pixelformats. The formats has been added in upstream Linux by commit 1d9215233958 ("media: uapi: v4l: Add generic 8-bit metadata format definitions") which got merged in Linux v6.10. The formats however are not yet available to userspace, as they have been made only available to the kernel by commit d69c8429ea80 ("media: uapi: v4l: Don't expose generic metadata formats to userspace") to let the line-based metadata support stabilize before allowing applications to use it. With the forthcoming completion of the line-based metadata upstreaming manually add the generic line based pixel format to prepare libcamera to support them.
