[Patch V3] UefiPayloadPkg: Add script to build UniversalPayload in UefiPayloadPkg

["duntan" <dun.tan@intel.com>]

V1: Add script to build UniversalPayload, which can be used after edksetup rebuild
The final UPL.elf will be located at root folder of edk2

V2: Revise the ouput directory of generated files and coding style in the script
