MdeModulePkg: DxeCore: Create PopulateMemoryTypeInformation Helper
In preparation for supporting shared memory bin logic in DXE
and PEI, create a PopulateMemoryTypeInformation() helper function.
This function searches for a Memory Type Information Hob and
populates an EFI_MEMORY_TYPE_INFORMATION struct with it.

Migrate CoreSetMemoryTypeInformationRange() to not use globals so

This temporarily moves the EFI_MEMORY_STATISTICS structure to

This will migrate to a different private header once that is included.

MdeModulePkg: Dxe Core: Split Memory Bin Logic Into Separate File
This commits splits out logic currently contained in
Gcd.c and Page.c to a new file called
MemoryBin.c. This is set up in preparation to
add support to PEI for memory bins (an S4 resume stability
feature).
MemoryBin.c takes all global state in as parameters so that
DXE core can use globals and PEI core can use HOBs.
There is no logic change here, just consolidating the
functionality to share with PEI.
This was requested not to be a library.

OvmfPkg: PlatformPei: Add PEI Memory Bin Support
This commit enables PEI memory bins in OVMF IA32X64 and
OVMF X64.
OVMF supports many different boot flows. The variable PEIM
is only dispatched when SMM_REQUIRE is TRUE. The early variable
store is not set up otherwise.
The PlatformPei PEIM requires the variable PPI be available
before creating the gEfiMemoryTypeInformationGuid HOB, in order
to use the BDS advertised bin sizes. If SMM_REQUIRE is FALSE,
it just produces the HOB.
PEI Core requires that the gEfiMemoryTypeInformationGuid HOB be
produced pre-mem PEI in order to set up the memory bins at the
start of post-mem PEI. PlatformPei is also the PEIM that installs
permanent memory.
As such, a depex on the variable PPI cannot be used, to support
the different flows. So, this commit splits the PlatformPei
initialization flow into two phases. The first phase completes
until memory bin initialization. If that returns success (either
because SMM_REQUIRE is FALSE or because the variable PPI was
already installed), phase 2 init is completed immediately and
no callback is created. If that fails, a callback is created
for the variable read PPI and phase 2 initialization is completed
after that.

ArmVirtPkg: MemoryInitPeim: Add PEI Memory Bin Support
This commit adds memory bin support to ArmVirtQemu. ArmVirtQemu
does not have a PEI variable driver, so it does not attempt
to update the bin size or location.
The bin sizes are also updated because they were very out of
date.
