Export ValidateBasicFields for Hypershift (#916)

In Hypershift we need to validate PerformanceProfile from NodePool
controller.
As a one-to-one relationship between NodePool and Performance Profile is
already enforced there is no need ( and no easy way ) to check for
PerformanceProfiles with duplicated selectors, so we just need to check
the fields.
