MdeModulePkg/ResetUtilityLib: Add a new API ResetSystemWithSubtype

Browse Source 
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=1458

Implement the new API ResetSystemWithSubtype. Depend on Uefi Spec
2.8 chapter 8.5.1, the ResetData is valid while the ResetStatus
is EFI_SUCCESS regardless of the ResetType. Also change the function
ResetPlatofrmSpecificGuid to directly call ResetSystemWithSubtype
to reduce the duplicated code.
