It is not necessary to have a PEI phase in the UEFI payload since no
specific PEI task is required. This patch adds a UefiPayloadEntry
driver to get UEFI Payload required information from the bootloaders,
convert them into a HOB list, load DXE core and transfer control to it.
Here is the change details:
1) Removed PEI phase, including Peicore, BlSupportPei, SecCore, etc.
2) Added UefiPayloadEntry driver. this is the only driver before DXE core.
3) Added Pure X64 support, dropped Pure IA32 (Could add later if required)
64bit payload with 32bit entry point is still supported.
4) Use one DSC file UefiPayloadPkg.dsc to support X64 and IA32X64 build.
Removed UefiPayloadIa32.dsc and UefiPayloadIa32X64.dsc
Tested with SBL and coreboot on QEMU.

2. Run "make menuconfig" in linux console to start Coreboot configuration surface.
3. In the Payload section,
- 1) Choose "An ELF executable payload" for the option of "Add a payload".
- 2) Type the path of payload image for the option of "Payload path and filename".
- 3) Select the option of "Use LZMA compression for payloads".
+ 1) Choose "Tianocore Payload" for the option of "Add a payload".
+ 2) Update the path of payload image for the option of "Tianocore binary".
+ 3) Choose "UEFIPayload" for the option of "Tianocore Payload".
4. If the graphics console is required in UEFI payload, enable framebuffer initialization in coreboot.
This could be done by enabling native graphics or using VGA BIOS option rom.
5. Build the coreboot firmware image.
