Add a new API ResetSystem in ResetSystemLib.
Implement a runtime library instance of ResetSystemLib.
The runtime library instance is base on the new API implementation.

Add a new API ResetSystem:
VOID
EFIAPI
ResetSystem (
  IN EFI_RESET_TYPE               ResetType,
  IN EFI_STATUS                   ResetStatus,
  IN UINTN                        DataSize,
  IN VOID                         *ResetData OPTIONAL
  )
The Consumer of ResetSystemLib can use this new API to reset
system with additional reset data.Because ResetSystemRuntimeDxe
has a same function name with it, change the function name from
ResetSystem to EfiRuntimeResetSystem(both ResetSystem and
EfiResetSystem are used in ResetSystemLiband RuntimeLib, and the
driver consumes these two library) in driver ResetSystemRuntimeDxe.

BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=1461

For now there is no ResetSystemLib instance that can be
linked against Runtime driver. And it's improper to extend
the existing DxeResetSystemLib to support Runtime driver
because no one converts gRT when entering RT phase.
