doc: Remove stale notes

[junrushao]

There was a note in TVM_FFI_DLL_EXPORT_TYPED_FUNC saying:

\note ExportName and Function must be different

which has been stale for a while. The system doesn't have the constraint as of today. This PR removes this line.

Code Review

This pull request removes a stale documentation note from the TVM_FFI_DLL_EXPORT_TYPED_FUNC macro. The note incorrectly stated that the ExportName and Function parameters must be different. As confirmed by existing test cases, this constraint is no longer valid. The change is correct and improves the accuracy of the documentation. I have no further comments.
