EmbeddedPkg/VirtualRealTimeClockLib: drop LibRtcVirtualNotifyEvent

The RealTimeClockLib class header in edk2 mistakenly declares a function
called LibRtcVirtualNotifyEvent(). No component ever calls this function
crossing module boundaries; all RealTimeClockLib instances in edk2 and
edk2-platforms are supposed to register (and do register) their
SetVirtualAddressMap() notification functions.

In particular, VirtualRealTimeClockLib *itself* doesn't even use
LibRtcVirtualNotifyEvent() -- the function is defined with an empty body,
clearly in an understandable, but misguided, attempt, to conform to the
(bogus) library interface. Remove the function.

Build-tested only (with "RiscVVirtQemu.dsc").
