UefiPayloadPkg: Simplify code logic

UefiPayloadPkg: Simplify code logic

A little overdesign about VisitAllPciInstances function, since there are
two call back functions. Simplify the code logic by combining the two call
back functions, and unused parameters.
Change the PROTOCOL_INSTANCE_CALLBACK to SIMPLE_PROTOCOL_INSTANCE_CALLBACK
because the former is also defined in OvmfPkg. Rename it to avoid confusion.
