REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3440

The definition of EFI_MM_RESERVED_MMRAM_REGION, according to PI Spec 1.5
is also referenced in EFI_PEI_MM_CONFIGURATION_PPI. Defining this
structure as is will enforce any potential usage of MM Configuration PPI
interface to include <Protocol/MmConfiguration.h>.

This change moves EFI_MM_RESERVED_MMRAM_REGION definition into PiMmCis.h,
which is already included in Protocol/MmConfiguration.h. It also paves
way for introducing Ppi/MmConfiguration.h with proper dependency.
