Support `Self` or suppress `clippy::use_self` warning

[mxk]

It's currently not possible to use name_of_type!(Self) to get the actual type name. If there is a way to support this, that would be great, but until then, it would be nice to automatically suppress clippy::use_self warning in the macro.

stringify!(Self) will always return Self - instead you may be able to use std::any::type_name::<Self>()
