Rollup merge of #94503 - joshtriplett:core-ffi-c, r=Amanieu
Provide C FFI types via core::ffi, not just in std Tracking issue: https://github.com/rust-lang/rust/issues/94501 The ability to interoperate with C code via FFI is not limited to crates using std; this allows using these types without std. The existing types in `std::os::raw` become type aliases for the ones in `core::ffi`. This uses type aliases rather than re-exports, to allow the std types to remain stable while the core types are unstable. This also moves the currently unstable `NonZero_` variants and `c_size_t`/`c_ssize_t`/`c_ptrdiff_t` types to `core::ffi`, while leaving them unstable. Historically, we didn't do this because these types are target-dependent. However, `core` itself is also target-dependent. `core` should not call any OS services, but it knows the target and the target's ABI.
