The current way to check if a feature flag is enabled regardless of FCV is:

if (featureFlag.isEnabled(
  [](auto& fcvGatedFlag) { return fcvGatedFlag.isEnabledAndIgnoreFCVUnsafe(); })) 

That can be more complex than necessary. 

We can change it to something like: 

if (featureFlag.isEnabled(kIgnoringFCV)) 

to make it easy to read. 

We should also change the linter to lint for `kIgnoringFCV` instead of the "(Ignore FCV check)" comment
