This function returns the version value associated with the driver specified by This.
Retrieves the version of the driver that is used by the EFI Boot Service ConnectController()
to sort the set of Driver Binding Protocols in order from highest priority to lowest priority.
For drivers that support the Driver Family Override Protocol, those drivers are sorted so that
the drivers with higher values returned by GetVersion() are high priority that drivers that
return lower values from GetVersion().
@param This A pointer to the EFI_DRIVER_FAMILY_OVERRIDE_PROTOCOL instance.

When installed, the Driver Family Override Protocol produces a GUID that represets
a family of drivers. Drivers with the same GUID are members of the same family
When drivers are connected to controllers, drivers with a higher revision value
in the same driver family are connected with a higher priority than drivers
with a lower revision value in the same driver family. The EFI Boot Service
Connect Controller uses five rules to build a prioritied list of drivers when
a request is made to connect a driver to a controller. The Driver Family Protocol
rule is between the Platform Specific Driver Override Protocol and above the
Bus Specific Driver Override Protocol
@param FamilyGuid A pointer to the GUID that represnets the family of drivers
that the driver producing this protocol is a member.
