Rollup merge of #111096 - AngelicosPhosphoros:overflow_checks_issue_91130, r=petrochenkov
Add support for `cfg(overflow_checks)`
This PR adds support for detecting if overflow checks are enabled in similar fashion as `debug_assertions` are detected. Possible use-case of this, for example, if we want to use checked integer casts in builds with overflow checks, e.g.
```rust
pub fn cast(val: usize)->u16 {
if cfg!(overflow_checks) {
val.try_into().unwrap()
}
else{
vas as _
}
}
```
Resolves #91130.
