Add checkasm coverage for the XYZ12LE to RGB48LE path via the ctx->xyz12Torgb48 hook. Integrate the test into the build and runner, exercise a variety of widths/heights, compare against the C reference, and benchmark when width is multiple of 4. This improves test coverage for the new function pointer in preparation for architecture-specific implementations in subsequent commits. Signed-off-by: Arpad Panyik <Arpad.Panyik@arm.com>
