MdeModulePkg/PiSmmCore: Add MemoryAttributes support.

The SMM memory attribute table concept is similar to UEFI
memory attribute table.

The new file MdeModulePkg/Core/PiSmmCore/MemoryAttributesTable.c
and the new code in MdeModulePkg/Core/PiSmmCore/Page.c
are based on the algorithms and implementation from
MdeModulePkg/Core/Dxe/Misc/MemoryAttributesTable.c
and MdeModulePkg/Core/Dxe/Mem/Page.c.

These new components are based on the Memory Attributes Table
feature from the UEFI Specification and the existing DXE Core
implementation that supports that feature.

This SMM MemoryAttributes table is produced at SmmEndOfDxe event.
So that the consumer (PiSmmCpu) may consult this table
to set memory attribute in page table.

This patch also installs LoadedImage protocol to SMM
protocol database, so that the SMM image info can be
got easily to construct the PiSmmMemoryAttributes table.
