UefiPayloadPkg: Use DynamicEx instead of Dynamic to pass PCD across binary
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.
Therefore, using DynamicEx instead of Dynamic.
Also, explicitly define some PCDs as DynamicEx, or their default type will
be Dynamic
