MdePkg: Add new definitions for Management Mode.

Browse Source 
In PI 1.5 version, system management mode name(SMM) has been changed
to Management Mode(MM). It impacts the current code which still use
SMM/Smram/SMI keywords. This patch add new definition which use
MM/MmRam/MMI keywords to follow new spec definitions.

/** @file
EFI MM Configuration Protocol as defined in the PI 1.5 specification.
This protocol is used to:
1) report the portions of MMRAM regions which cannot be used for the MMRAM heap.
2) register the MM Foundation entry point with the processor code. The entry
point will be invoked by the MM processor entry code.
