cr.ui.Oobe.toggleStep

Same prefix for other functions.

Done.

I think it makes sense to comment these calls like
showError, clearErrors, showConnectingStatus till they're enabled in JS.

Some of them like showError/showConnectingStatus don't even have proper mocks.

Done.

You don't need this string.

I guess these lists will be initialized in Initialize instead.
