[edk2-devel] [Patch V3] UefiPayloadPkg: Use DynamicEx instead of Dynamic to pass PCD across binary

[Zhiguang Liu]

V1:
When passing PCD database from Edk2 boot loader to Universal Payload, the local
token number in boot loader PCD database can be different with that in Payload
PCD database.
Dynamic PCD directly use local token number, while DynamicEx will search token number
by Guid and ExTokenNumber, which are unique pair and can make sure finding the correct
token number in boot loader's PCD database
V2:
Remove PCD PcdFlashNvStorageFtwWorkingBase and PcdFlashNvStorageFtwSpareBase, because they
are not consumed by any modules.
Explicitly define some PCDs as DynamicEx, or their default type will be Dynamic

V3:
Not remove some PCDs for they will be consumed soon
