sync patch r10180, r10191, r10628, r10720, r10772 from main trunk.

1. Update to use 1 EFI Variable per NIC (instead of converge all NIC configuration into
   one EFI Variable), this remove the limitation that max NIC configuration will depend
   on PcdMaxVariableSize.
2. Remove unnecessary Unload function EfiIp4ConfigUnload (use default Unload function
   NetLibDefaultUnload instead), remove global array for NIC handle tracking since it's
   driver model driver.
3. Add Ip4Config Variable reclaim to HiiConfigAccess.RouteConfig() to remove variable for
   NIC which has been removed from the system.
4. Update HiiConfigAccess.ExtractConfig interface produced by the following drivers to
   support NULL request string and ConfigHdr request string without any request element
   according to the latest UEFI specification.
5. Update the title Network Configuration to IPv4 Network Configuration.
6. Fix one issue: Some last IP settings may be lost when IP setting was re-set.
7. Fix a typo in Ip4ConfigDriverBindingStart(): it should be 
   gEfiManagedNetworkServiceBindingProtocolGuid instead of gEfiManagedNetworkProtocolGuid.
