/**
* @brief Converts YUYV image format to RGB planar image format.
*
* This function takes a YUYV image and converts it to RGB planar image format
* using ColorConvertYUYVToRGBPlanarKernel HIP kernel.
* The YUYV image is represented as a packed format where each pixel consists of
* one luminance (Y) component and two chrominance (U and V) components. The RGB
* planar image format represents each color component (R, G, and B) in separate
* planes.
*
* @param stream The HIP stream to execute the kernel on.
* @param dst_width The width of the destination RGB planar image.
* @param dst_height The height of the destination RGB planar image.
* @param dst_image_r Pointer to the destination red (R) component image plane.
* @param dst_image_g Pointer to the destination green (G) component image plane.
* @param dst_image_b Pointer to the destination blue (B) component image plane.
* @param dst_image_stride_in_bytes The stride (in bytes) between consecutive rows of the destination image.
* @param src_image Pointer to the source YUYV image.
* @param src_image_stride_in_bytes The stride (in bytes) between consecutive rows of the source image.
