UefiPayloadPkg: Update logic of fetching Processor Physical Address size

UefiPayloadEntry utilizes CPUID 0x80000008 leaf to retrieve the Processor's
Physical Address size for X86 architecture. To enable support for multiple
architectures, replace the direct implementation with an architecture-level
function provided by the UefiCpuPkg library, abstracting the underlying details.
