Rename the file PiSmmCpuDxeSmm.h to PiSmmCpuCommon.h to facilitate
common usage in both SMM and MM. The renamed file PiSmmCpuCommon.h
will be utilized for both modes in subsequent patches.
No function impact.

Rename SmiDefaultPFHandler to SmiProfileMapPFAddress
and move the implementation to SmmProfileArch.c since
it only will be used when SMM profile is enabled.

PiSmmCpuDxeSmm consumes SmmAttributesTable and setup page table:
1) Code region is marked as read-only and Data region is non-executable,
if the PE image is 4K aligned.
2) Important data structure is set to RO, such as GDT/IDT.
3) SmmSaveState is set to non-executable,
and SmmEntrypoint is set to read-only.
4) If static page is supported, page table is read-only.
We use page table to protect other components, and itself.
If we use dynamic paging, we can still provide *partial* protection.
And hope page table is not modified by other components.
The XD enabling code is moved to SmiEntry to let NX take effect.

So that we can use write-protection for code later.
This is REPOST.
It includes the bug fix from "Paolo Bonzini" <pbonzini@redhat.com>:
Title: fix generation of 32-bit PAE page tables
"Bits 1 and 2 are reserved in 32-bit PAE Page Directory Pointer Table
Entries (PDPTEs); see Table 4-8 in the SDM. With VMX extended page
tables, the processor notices and fails the VM entry as soon as CR0.PG
is set to 1."
And thanks "Laszlo Ersek" <lersek@redhat.com> to validate the fix.

Add module that initializes a CPU for the SMM environment and
installs the first level SMI handler. This module along with the
SMM IPL and SMM Core provide the services required for
DXE_SMM_DRIVERS to register hardware and software SMI handlers.
CPU specific features are abstracted through the SmmCpuFeaturesLib
Platform specific features are abstracted through the
SmmCpuPlatformHookLib
Several PCDs are added to enable/disable features and configure
settings for the PiSmmCpuDxeSmm module
