MdeModulePkg PCD: Add DynamicEx PcdVpdBaseAddress64 for non SPI platform
https://bugzilla.tianocore.org/show_bug.cgi?id=1356
Current PcdVpdBaseAddress is 32bit static Pcd. NON SPI platform needs to
configure it as Dynamic PCD. Emulator platform (such as NT32) may set its
value to 64bit address.
To meet with this usage, 64bit DynamicEx PcdVpdBaseAddress64 is introduced.
If its value is not zero, it will be used.
If its value is zero, static PcdVpdBaseAddress will be used.
When NON SPI platform enables VPD PCD, they need to set PcdVpdBaseAddress64.
