MdeModulePkg: stop abusing EFI_EVENT for protocol notify registration

Browse Source 
EfiCreateProtocolNotifyEvent() takes a (VOID**) for "Registration",
similarly to gBS->RegisterProtocolNotify(). We should pass the address of
an actual pointer-to-VOID, and not the address of an EFI_EVENT. EFI_EVENT
just happens to be specified as (VOID*), and has nothing to do with the
registration.

The same applies to gMmst->MmRegisterProtocolNotify().

"mFtwRegistration", "mFvRegistration", and "mFvbRegistration" are used for
nothing else.

This change is a no-op in practice; it's a semantic improvement.
