Could we dump the sass result ourselves after getting it?

I think the reason for adding callback functions here is that we cannot obtain the intermediate results (LLVM IR, etc.) by subclass `SerializeGPUModuleBase` (maybe we can override `ModuleToObject::run()`, but this will cause code duplication, which is not a good solution).
