Why is there no `math.pow()` function?

The pow function should be uses as an overloaded method of the SIMD struct. However, if you really need a dedicated function for that, here is an unrecommended way to do so:

```mojo
from builtin import simd

fn main() raises:
    var base = SIMD[DType.float32, 4](-3.0, -2.0, 2.0, 3.0)
    var exp = SIMD[DType.float32, 4](3.0, 3.0, 3.0, 3.0)
    var res = simd._powf(base, exp)
    print(res) # SIMD[DType.float32, 4](-27.0, -8.0, 8.0, 27.0)

```

Where is the `simd._powf()` function documented?

Ah, now i see there is a `builtin`/`math.pow()` function. For the sake of completeness, what about adding a similar function to the `math` package as well?

We do have a free function `pow` though.
