Rollup merge of #112136 - clarfonthey:ffi-c_str, r=cuviper
Add std::ffi::c_str module

ACP: rust-lang/libs-team#134

`std::ffi` docs before change:
![Structs: VaList, VaListImpl, CStr, CString, FromBytesWithNulError, FromVecWithNulError, IntoStringError, NulError, OsStr, OsString](https://github.com/rust-lang/rust/assets/15850505/b2cf3534-30f9-4ef0-a655-bacdc3a19e17)

`std::ffi` docs after change:
![Re-exports: self::c_str::{FromBytesWithNulError, FromBytesUntilNulError, FromVecWithNulError, NulError, IntoStringError} ; Modules: c_str ; Structs: VaList, VaListImpl, CStr, CString, OsStr, OsString](https://github.com/rust-lang/rust/assets/15850505/23aa6964-da7a-4942-bbf7-42bde2146f9e)

(note: I'm omitting the `c_int`, etc. stuff from the screenshots since it's the same in both. this doesn't just delete those types)

d6b7480c2a Stabilize core::ffi::CStr, alloc::ffi::CString, and friends
Stabilize the `core_c_str` and `alloc_c_string` feature gates.

Change `std::ffi` to re-export these types rather than creating type
aliases, since they now have matching stability.

b454991ac4 Finish bumping stage0
It looks like the last time had left some remaining cfg's -- which made me think
that the stage0 bump was actually successful. This brings us to a released 1.62
beta though.
