In the system boot phase, if OS postpone onlining some CPU
until later, the sec page tables could be overwritten.
So, TDVF needs to reserve the initial page tables that would be
used by APs on Mailbox wakeup.

The BSP's APIC mode is synced to all APs in CollectProcessorCount().
So, it's safe to skip the X2 APIC enabling in AutoEnableX2Apic() which
runs later when BSP's APIC mode is X2 APIC already.

The change saves the BSP's initial APIC mode and syncs to all APs
in first time wakeup. It allows certain platforms to switch to X2 APIC
as early as possible and also independent on CpuFeaturePei/Dxe.
The platform should switch BSP to X2 APIC mode first before the
CpuMpPeim runs.

It's very confusing that auto X2 APIC enabling and APIC ID sorting
are all performed inside CollectProcessorCount().
The change is to separate the X2 APIC enabling to AutoEnableX2Apic()
and call that from MpInitLibInitialize().
SortApicId() is called from MpInitLibInitialize() as well.

The motivation of this change is to simplify the logic in
StandaloneMmIpl when allocating the memory for SMM profile data.
IPL does not need to detect the CPU feature regarding MSR DS
Area. That change requires the PCD value contains the MSR DS
Area. So, the size of SmmProfileData will be simplified to the
PcdCpuSmmProfileSize directly.
mMsrDsAreaSize will be within the PcdCpuSmmProfileSize if
mBtsSupported is TRUE.

For MM, gMmProfileDataHobGuid Memory Allocation HOB is defined to
indicate SMM profile feature enabled or not. If the HOB exist, SMM
profile base address and size will be returned in the HOB, so no need
to consume the PcdCpuSmmProfileEnable feature PCD to check enable or
disable.
To achieve above purpose, Add the IsSmmProfileEnabled () function.
With this change, Both MM and SMM can use the new function for
SMM profile feature check.

This patch is to refine the updatePageTable logic for DxeSmm.
For DxeSmm, PageTable will be updated in the first SMI when SMM
ready to lock happen:
IF SMM Profile is TRUE:
1. Mark mProtectionMemRange attribute: SmrrBase:Present, SMM
profile base:Present&Nx, MMRAM ranges:Present, MMIO ranges:
Present&Nx.
2. Mark the ranges not in mProtectionMemRange as RP (non-present).
IF SMM Profile is FALSE:
1. Mark Non-MMRAM ranges as NX.
2. IF RestrictedMemoryAccess is TRUE:
Forbidden Address mark as RP (IsUefiPageNotPresent is TRUE).

For SMM:

1. Create default Page
2. update the page table in the first SMI when SMM ready to lock
happen
This patch to refactor the GenSmmPageTable() function to create the
default Page Table for Both SMM and MM:
1. Create NonMmram MemoryRegion
2. Gen NonMmram MemoryRegion PageTable
3. Gen MMRAM Range PageTable
4. Consider PcdCpuSmmStackGuard & PcdNullPointerDetectionPropertyMask

Meanwhile, mXdSupported needs to be initialized before GenSmmPageTable since
it's required by GenSmmPageTable function. So, move the mXdSupported init
from CheckFeatureSupported to the common EntryPoint function.

Different from SMM Core, Standalone MM Core produces MM MemoryAttributes
table at the end of MmDriverDispatchHandler() when all the drivers are

Then the MM CPU driver will consumes the table to set memory attribute

Defer the dispatch of the remaining MM drivers once the CPU driver has
been dispatched.
In MmDispatcher, return immediately if the MM Entry Point was registered.
Then the MM IPL will reinvoke the MM Core Dispatcher. This is required
so MM Mode may be enabled as soon as all the dependent MM Drivers for MM
Mode have been dispatched.
Introduce a FeatureFlag PCD to control if MmDispatcher returns or not
when MmEntryPointPoint is registered. Default value is FALSE.

mMmramRanges and mMmramRangeCount are the global variables that are
used to cache the MMRAM Ranges info, but they are not used in MM Core.
Therefore, remove mMmramRanges and mMmramRangeCount.

MM_CORE_PRIVATE_DATA is not used as shared structures between MM IPL
and MM Core, therefore clean up definition for MM_CORE_PRIVATE_DATA.
