Rollup merge of rust-lang#104954 - vincenzopalazzo:macros/prinf, r=estebank

make simple check of prinf function

Fixes rust-lang#92898

With this commit we start to make some simple
check when the name resolution fails, and
we generate some helper messages in case the
name is a C name like in the case of the `printf`
and suggest the correct rust method.
