HarmonyOS OH_ImageSourceNative_CreateFromData设置图片，报错[ImageSource]check mismatched format

在ArkTS中，从pixelmap获取的buffer已经是解码后的数据，不应该传入imagesource，imagesource是用来对未解码数据进行解码的。此处应该直接创建PixelMap：

void *buffer_data = NULL;
size_t byte_length = 0;
napi_get_arraybuffer_info(env, args[0], &buffer_data, &byte_length);
uint8_t* data = static_cast<uint8_t*>(buffer_data);

OH_Pixelmap_InitializationOptions *createOpts;

OH_PixelmapInitializationOptions_Create(&createOpts);
OH_PixelmapInitializationOptions_SetWidth(createOpts, 20);
OH_PixelmapInitializationOptions_SetHeight(createOpts, 20);
OH_PixelmapInitializationOptions_SetPixelFormat(createOpts, PIXEL_FORMAT_RGBA_8888);
OH_PixelmapInitializationOptions_SetAlphaType(createOpts, PIXELMAP_ALPHA_TYPE_UNKNOWN);
