MdeModulePkg/Core/Dxe: Initialize GCD before RT memory allocations
Update the DxeMain initialization order to initialize GCD
services before any runtime allocations are performed. This
is required to prevent runtime data fragmentation when the
UEFI System Table and UEFI Runtime Service Table are allocated
before both the memory and GCD services are initialized.

MdeModulePkg/Core/Dxe: Set MemoryTypeInfo bin range from HOB
Provide an optional method for PEI to declare a specific address
range to use for the Memory Type Information bins. The current
algorithm uses heuristics that tends to place the Memory Type
Information bins in the same location, but memory configuration
changes across boots or algorithm changes across a firmware
updates could potentially change the Memory Type Information bin
location. If the bin locations move across an S4 save/resume
cycle, then the S4 resume may fail. Enabling this feature
increases the number of scenarios that an S4 resume operation
may succeed.
If the HOB List contains a Resource Descriptor HOB that
describes tested system memory and has an Owner GUID of
gEfiMemoryTypeInformationGuid, then use the address range
described by the Resource Descriptor HOB as the preferred
location of the Memory Type Information bins. If this HOB is
not detected, then the current behavior is preserved.
The HOB with an Owner GUID of gEfiMemoryTypeInformationGuid
is ignored for the following conditions:
* The HOB with an Owner GUID of gEfiMemoryTypeInformationGuid
is smaller than the Memory Type Information bins.
* The HOB list contains more than one Resource Descriptor HOB
with an owner GUID of gEfiMemoryTypeInformationGuid.
* The Resource Descriptor HOB with an Owner GUID of
gEfiMemoryTypeInformationGuid is the same Resource Descriptor
HOB that that describes the PHIT memory range.
