* Avoid negative input to sqrt() (#6397)

- The calculation of `k` is not numerically robust when done in FP16 and might generate a negative value.
- This can be observed as rendering artifacts on Mali drivers newer than Bifrost/Valhall R21.
- This commit fixes this by by clamping `k` to [0, inf] before the `sqrt()`.
- On Mali-G77 the clamp compiles down to a free output modifier on the previous instruction, so there's no performance impact.
