generator: Emit new c"" CStr literals

These will land in Rust 1.76 and automatically append a `\0` terminator
in the compiler without having to have a checked or `unsafe`-unchecked
constructor on `CStr`.

Hacking in an invalid `\0` anywhere in the string is disallowed with a
compiler error.

Note that `proc-macro`, and by extension `proc-macro2` only has support
for parsing this literal, but not for emitting it yet.
