MdeModulePkg/PiSmmCore: Add SmiHandlerProfile support. 

1) SmmCore maintains the root SMI handler and NULL SMI handler
database.
2) SmmCore consumes PcdSmiHandlerProfilePropertyMask to decide
if SmmCore need support SMI handler profile.
If SMI handler profile is supported, the SmmCore installs
SMI handler profile protocol and SMI handler profile
communication handler.
3) SMI handler profile protocol will record the hardware SMI
handler profile registered by SmmChildDispatcher.
4) SMI handler profile communication handler will return all
SMI handler profile info (NULL SMI handler, GUID SMI handler,
and hardware SMI handler)
