STYLE: Replace NumericTraits<float> ZeroValue() and OneValue() calls

Replaced `NumericTraits<float>::ZeroValue()` calls by `0.0f`. Also
replaced the one call to `itk::NumericTraits<float>::OneValue()`, from
inside itkMathTest.

Follow-up to similar commits for `double`, but now specific for `float`,
as suggested by Dženan Zukić.
