(rustdoc) [src] link for types defined by macros shows invocation, not defintion

Previously the [src] link on types defined by a macro pointed to the macro definition.

This pr makes the Clean-Implementation for Spans aware of macro defined types, so that the link points to the invocation instead.

I'm not totally sure if it's okay to add the 'macro awareness' in the Clean-Implementation, because it erases that knowledge for all following code. Maybe it would be more sensible to add the check only for the link generation at 25f6938da4/src/librustdoc/html/render/mod.rs (L1619)

Closes #39726.
