Subject: [PATCH v4 00/13] Part 2 patch set to add LoongArch support into UefiCpuPkg

This patch set adjusted some order in UefiCpuPig alphabetically, added
LoongArch libraries and drivers into UefiCpuPkg, it is a continuation of
the first patch series v8 submitted at
https://edk2.groups.io/g/devel/message/114526.

And also separated from https://edk2.groups.io/g/devel/message/116583.

This series only contents the changes for UefiCpuPkg.

Patch1-Patch4: Reorder some INF files located in UefiCpuPkg
alphabetically.

Patch5-Patch13: Added Timer, CpuMmuLib, CpuMmuInitLib, MpInitLib, CpuDxe
for LoongArch, and added some PCD and header files requested by the
above libraries and drivers.

Modfied modules: UefiCpuPkg

V1 -> V2:
1. Removed PcdCpuMmuIsEnabled.
2. Removed API GetMemoryRegionAttributes API as it is no longer needed.
3. Patch3, added two empty line in DXE and PEI INF files.
4. Patch5, added the Status check in GetTimeInnanoSecond function.
5. Separated into two series, this is series one, and the second one is
OvmfPkg.

V2 -> V3:
1. Remove CpuMmuInitLib.
2. Added a new GUID HOB named PROCESSOR_RESOURCE_HOG_GUID.
3. Following Ray suggest, adjust CpuMmuLib API, rename the API name.
4. Rename the PcdCpuExceptionVectorBaseAddress to
PcdLoongArch64ExceptionVectorBaseAddress.
5. Enable CpuMmio2Dxe in LoongArch.

V3 -> V4:
Patch 10, use flexible arrays in PROCESSOR_RESOURCE_DATA.
