Auto merge of #97367 - WaffleLapkin:stabilize_checked_slice_to_str_conv, r=dtolnay
Stabilize checked slice->str conversion functions
This PR stabilizes the following APIs as `const` functions in Rust 1.63:
```rust
// core::str
pub const fn from_utf8(v: &[u8]) -> Result<&str, Utf8Error>;
impl Utf8Error {
pub const fn valid_up_to(&self) -> usize;
pub const fn error_len(&self) -> Option<usize>;
}
```
Note that the `from_utf8_mut` function is not stabilized as unique references (`&mut _`) are [unstable in const context].
