Remove the underscored public protocols from overlays

Browse Source 
These protocols were introduced to work around the problem where
compiler could not correctly handle instance of multiple @available

applied to the same member.

Now that the compiler issues has been fixed, it is the right time to get
rid of the workarounds.
