To implement swift_errorBridgingInfo, the Foundation overlay needs to import private runtime headers. Now that we cannot statically link the Foundation overlay, there is no point to keeping this workaround in the overlay. Remove it and let the runtime individually dlsym these things when it needs them.
This is more or less a revert of #16677.
