UefiPayloadPkg: Handle ordering issue with option node 

Option node provides info that is to be consumed by during
metadata creation for other nodes like root bridge; pci-enum-done
etc. Handle that dependency by storing option values in a variable
and then apply it during post processing. Ideally such cross node
dependency should be avoided in design. Scope for futher improvements.
