Recent Linux kernel accepts acpi_rsdp=0x.. in kernel command line.
This will make Linux kernel look for ACPI RSDP address in the kernel
commad line first prior to in DMI or F-segment.

This will allow OsLoader payload to boot to 64-bit kernel entry point.
If CPU supports 64-bit mode and a kernel image has 64-bit entry point,
OsLoader will switch to 64-bit long mode and jump to the 64-bit entry
point. Otherwise, continue to boot to 32-bit entry point.
- Ported necessary code from EDK2 VitualMemory.c in MdeModulePkg
- Moved PagingLib from BootloaderCorePkg to BootloaderCommonPkg
- Removed unused FlushCacheLine
- TBD: 64-bit IDT
Next step is to support 64-bit Payload.
- 32-bit compatible mode
- 64-bit CryptoLib
- etc.

This will fully support PatchCheck.py.
- Remove all trailing whitespace
- Convert LF to CRLF by default
- Update EFI_D_* to DEBUG_*
- Re-enable CRLF check in PatchCheck.py

OsLoader has the capability to boot a Linux kernel. However, to support
LinuxBoot type of payload, it is required to load kernel in Stage2. This
patch abstracts the standard Linux loading logic into common LinuxLib
class so that it can be linked in Stage2 or Payload such as OsLoader.
A new PcdLinuxPayloadEnabled is introduced to control if this feature
should be enabled or not.
To boot a Linux kernel from Stage2, it is required to put the command
line file and kernel image into the EPAYLOAD container during the build.
And the PayloadId CFGDATA needs to be set to 'LINX'.
For example:
python BuildLoader.py build qemu
-p OsLoader.efi::Lz4;vmlinuz:LINX:Dummy;cmdline.txt:CMDL:Dummy
vmlinuz and cmdkube.txt need to be copied to PayloadPkg/PayloadBins
folder. If kernel size cannot fit into EPAYLOAD, EPAYLOAD_SIZE in
BoardConfig.py needs to be adjusted accordingly.
