DISPATCH_DTYPE_TO_TEMPLATE

#define DISPATCH_DTYPE_TO_TEMPLATE	(		DTYPE,
			...
	)

Call a numerical templated function based on Dtype. Wrap the function to a lambda function to use DISPATCH_DTYPE_TO_TEMPLATE.

Before: if (dtype == core::Float32) { func<float>(args); } else if (dtype == core::Float64) { func<double>(args); } else ...

Now: DISPATCH_DTYPE_TO_TEMPLATE(dtype, [&]() { func<scalar_t>(args); });
