EmbeddedPkg/RealTimeClockLib: drop LibRtcVirtualNotifyEvent from lib class

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.

At this point, the word "LibRtcVirtualNotifyEvent" no longer occurs in any
of edk2, edk2-platforms, even edk2-non-osi, except the library class
header proper. Remove the LibRtcVirtualNotifyEvent() function declaration.

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