Feature gate: #![feature(proc_macro_c_str_literals)]

This is a tracking issue for C String literals in proc macros under #105723 and #118560, with an implementation in #119651.

This feature adds an API to construct a proc_macro::Literal C string directly.

Public API

let lit: Literal = Literal::c_string(&CString::new("Hello, world!").unwrap());

c_str_literals have been re-stabilized, I think this can now be considered for stabilization.

@rust-lang/libs-api:
@rfcbot fcp merge

Literal::c_string(&CString::new("Hello, world!").unwrap()) constructs the literal c"Hello, world!".

C-string literals stabilized recently in Rust 1.77.
