SmiHandlerUnRegister() validates the DispatchHandle by checking
whether the first 32bit matches to a certain signature
(SMI_HANDLER_SIGNATURE).
But if a caller calls *UnRegister() twice and the memory freed by
first call still contains the signature, the second call may hang.
The patch fixes this issue by locating the DispatchHandle
in all SMI handlers, instead of checking the signature.

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)

1. If at least one of the handlers returns EFI_WARN_INTERRUPT_SOURCE_QUIESCED or EFI_SUCCESS then the function will return EFI_SUCCESS.
If a handler returns EFI_SUCCESS and HandlerType is not NULL then no additional handlers will be processed.
2. If a handler returns EFI_INTERRUPT_PENDING and HandlerType is not NULL then no additional handlers will be processed and EFI_INTERRUPT_PENDING will be returned.
