Add no_std compatible ceil method (#18498)

Browse Source 
# Objective


[`f32::ceil`](https://doc.rust-lang.org/std/primitive.f32.html#method.ceil)
is not available in `core`. We have `floor` in `bevy_math::ops`, but no
equivalent for `floor`.

## Solution

Add `ops::ceil` for `no_std` compatibility.
