v5:
If PcdCpuMaxLogicalProcessorNumber is set to 1 on UP system,
MpInitLibInitialize() will be invoked. This is one bug, we need to
call MpInitLibInitialize() always and get the BSP information.
Just to remove PcdCpuMaxLogicalProcessorNumber() consuming from this
driver.

SetMemoryAttributes() will sync BSP's MTRRs settings to all APs by StartupAllAPs
service in serial mode. It may caused much performance impact if there are too
much processors in system. This update is to invoke StartupAllAps in parallel
mode. IA32 SDM does suggest to program MTRRs in parallel mode.

The PiSmmCpuDxeSmm module makes some assumptions about GDT selectors
that are based on the GDT layout from the DxeIplPeim. For example,
the protected mode entry code and (where appropriate) the long mode
entry code in the UefiCpuPkg/PiSmmCpuDxeSmm/*/MpFuncs.* assembly
files, which are used during S3 resume, open-code segment selector
values that depend on DxeIplPeim's GDT layout.
This updates the CpuDxe module to use the same GDT layout as the
DxeIplPeim. This enables modules that are dispatched after
CpuDxe to find, and potentially save and restore, a GDT layout that
matches that of DxeIplPeim. The DxeIplPeim has a 2 GDT entries for
data selectors that are identical. These are LINEAR_SEL (GDT Offset
0x08)and LINEAR_DATA64_SEL (GDT offset 0x30). LINEAL_SEL is used for
for IA32 DXE and the LINEAR_DATA64_SEL is used for X64 DXE. This
duplicate data selector was added to the CpuDxe module to keep the
GDT and all selectors consistent.
Using a consistent GDT also improves debug experience.

The Quark_EDKII_v1.1.0/IA32FamilyCpuBasePkg/CpuArchDxe
driver applies any MTRR changes to APs, if the
EFI_MP_SERVICES_PROTOCOL is available. We should do the same.
Additionally, the broadcast should occur at MP startup as well,
not only when MTRR settings are changed. The inspiration is
taken from
Quark_EDKII_v1.1.0/IA32FamilyCpuBasePkg/CpuMpDxe/
(see the EarlyMpInit() function and its call sites in
"ProcessorConfig.c").

Address a race condition in first call to StartupAllAPs() with
SingleThread set to TRUE in the MP initialization. If the APs
have not entered their idle loop before StartupAllAPs() is called,
then some of the APs will be in an unexpected state, and
StartupAllAPs() will hang. This is the hang condition that is
only seen when SingleThread parameter is set to TRUE and
StartupAllAPs() is called very shortly after mAPsAlreadyInitFinished
is set to TRUE that releases the APs to complete their initialization.
An internal function has been added to check if all APs are in the
sleeping state in their idle loop. On the first call to
StartupAllAPs(), this internal function is used in a loop to make
sure the APs are in a state that is compatible with the use of
StartupAllAPs(). PcdCpuApInitTimeOutInMicroSeconds is used as the
maximum wait time for the APs to enter their idle loop. If all
APs have not entered their idle loop within the timeout, then
an ASSERT() is generated.
