Rollup merge of #128735 - jieyouxu:pr-120176-revive, r=cjgillot 
Add a special case for `CStr`/`CString` in the `improper_ctypes` lint

Revives #120176. Just needed to bless a test and fix an argument, but seemed reasonable to me otherwise.

Instead of saying to "consider adding a `#[repr(C)]` or `#[repr(transparent)]` attribute to this struct", we now tell users to "Use `*const ffi::c_char` instead, and pass the value from `CStr::as_ptr()`" when the type involved is a `CStr` or a `CString`.

The suggestion is not made for `&mut CString` or `*mut CString`.

r? ``````@cjgillot`````` (since you were the reviewer of the original PR #120176, but feel free to reroll)
