elm_macros: fix for lack of precision with double due to order of operation.
Summary: The numerical formula below is calculated with the double type. -> ELM_SCALE_SIZE(x) (int)(((double)(x) / elm_app_base_scale_get()) * elm_config_scale_get()) But if number of significant figure of the return value goes over 15, the epsilon error will happen. Because of that, it is better to divide to do later.
