Rollup merge of #94455 - jhpratt:stabilize-int_roundings, r=joshtriplett

Partially stabilize `int_roundings`

This stabilizes the following:

```rust
impl uX {
    pub const fn div_ceil(self, rhs: Self) -> Self;
    pub const fn next_multiple_of(self, rhs: Self) -> Self;
    pub const fn checked_next_multiple_of(self, rhs: Self) -> Option<Self>;
}
```

This feature is tracked in #88581.
