UefiPayloadPkg/PayloadEntry: Inherit 4/5-level paging from bootloader
The patch removes the dep on PcdUse5LevelPageTable.
Now the payload inherits the 5-level paging setting from
bootloader in IA-32e mode and uses 4-level paging in
legacy protected mode.
This fix the potential issue when bootloader enables 5-level paging
but 64bit payload sets 4-level page table to CR3 resulting CPU
exception because PcdUse5LevelPageTable is FALSE.
