ArmPkg/Gic: force GIC driver to run before CPU arch protocol driver
Currently, the GIC driver has a static dependency on the CPU arch protocol
driver, so it can register its IRQ handler at init time. This means there
is a window between dispatch of the CPU driver and dispatch of the GIC
driver where any unexpected GIC state may trigger an interrupt which we
are not set up to handle yet. Note that this is even the case if we enter
UEFI with interrupts disabled at the CPU, given that any TPL manipulation
involving TPL_HIGH_LEVEL will unconditionally enable IRQs at the CPU side
regardless of whether they were enabled to begin with (but only as soon as
the CPU arch protocol is actually installed)
So let's reorder the GIC driver with the CPU driver, and let it run its
initialization that puts the GIC into a known state before enabling
interrupts. Move its installation of its IRQ handler to a protocol notify
callback on the CPU arch protocol so that it runs as soon as it becomes
available.

SafeIntLib provides helper functions to prevent integer overflow
during type conversion, addition, subtraction, and multiplication.
Conversion Functions
====================
* Converting from a signed type to an unsigned type of the same
size, or vice-versa.
* Converting to a smaller type that could possibly overflow.
* Converting from a signed type to a larger unsigned type.
Unsigned Addition, Subtraction, Multiplication
===============================================
* Unsigned integer math functions protect from overflow and
underflow (in case of subtraction).
Signed Addition, Subtraction, Multiplication
============================================
* Strongly consider using unsigned numbers.
* Signed numbers are often used where unsigned numbers should
be used. For example file sizes and array indices should always
be unsigned. Subtracting a larger positive signed number from a
smaller positive signed number with SafeInt32Sub() will succeed,
producing a negative number, that then must not be used as an
array index (but can occasionally be used as a pointer index.)
Similarly for adding a larger magnitude negative number to a
smaller magnitude positive number.
* SafeIntLib does not protect you from such errors. It tells you
if your integer operations overflowed, not if you are doing the
right thing with your non-overflowed integers.
* Likewise you can overflow a buffer with a non-overflowed
unsigned index.

MdeModulePkg/PciBusDxe: Install PciEnumerationComplete after PciIo
Per PI spec, the PciEnumerationComplete protocol installation
should be after PciIo installation.
Today's implementation installs the PciEnumerationComplete
after hardware enumeration is completed, but before PciIo
installation.
The change corrects the spec/implementation gap.
The change also benefits certain implementation that depends on
the PciIo handle in PciEnumerationComplete callback.

UefiCpuPkg/MtrrLib: Add comments to recommend to use batch-set API
MtrrSetMemoryAttributesInMtrrSettings() is a batch-set API.
When setting multiple ranges of memory attributes, the single-set
API (MtrrSetMemoryAttributeInMtrrSettings and MtrrSetMemoryAttribute)
may fail, but batch-set API may succeed.
Add comments to recommend caller to use batch-set API when setting
multiple ranges.

UefiCpuPkg/PeiMpLib: Fix a system hang-in-pei issue.
GetWakeupBuffer() tries to find a below-1M free memory, it checks
whether the memory is allocated already in
CheckOverlapWithAllocatedBuffer(). When there is a memory allocation
hob (base = 0xff_00000000, size = 0x10000000),
CheckOverlapWithAllocateBuffer() truncates the base to 0 which causes
it always returns TRUE so GetWakeupBuffer() fails to find a below-1MB
memory.
The patch fixes this issue by using UINT64 type.
