Rollup merge of #100291 - WaffleLapkin:cstr_const_methods, r=oli-obk 
constify some `CStr` methods

This PR marks the following public APIs as `const`:
```rust
impl CStr {
    // feature(const_cstr_from_bytes)
    pub const fn from_bytes_until_nul(bytes: &[u8]) -> Result<&CStr, FromBytesUntilNulError>;
    pub const fn from_bytes_with_nul(bytes: &[u8]) -> Result<&Self, FromBytesWithNulError>;

    // feature(const_cstr_to_bytes)
    pub const fn to_bytes(&self) -> &[u8];
    pub const fn to_bytes_with_nul(&self) -> &[u8];
    pub const fn to_str(&self) -> Result<&str, str::Utf8Error>;
}
```

r? ```@oli-obk``` (use of `const_eval_select` :P )
