 * @brief Prints out information about the sycl::platform argument.
 *
 * The helper function is used to print metadata about a given platform. The
 * amount of information printed out is controlled by the verbosity level.
 *
 * Verbosity level 0: Prints only the name of the platform.
 * Verbosity level 1: Prints the name, version, vendor, backend, number of
 *                    devices in the platform.
 * Verbosity level 2: Prints everything in level 1 and also prints the name,
 *                    version, and filter string for each device in the
 *                    platform.
 *
 * @param    PRef           A #DPCTLSyclPlatformRef opaque pointer.
 * @param    verbosity      Verbosilty level to control how much information is
 *                          printed out.
