Update existing `std::str::*` lints to also check `inherent_str_constructors`

[tgross35]

Description

A few clippy lints make use of the str_from_utf8* diagnostic items. Since recently, there is now a new set of diagnostic items str_inherent_from_utf8* associated with the inherent_str_constructors feature rust-lang/rust#131114, which should be checked in the same way.

See rust-lang/rust#137101 for the rustc update.

I think this should be pretty easy:

When I search for str_from_utf8 in the code, I found the issue might have been solved. I found this commit.

Ah, I opened this too late then! Thanks for finding that.
