SecurityPkg Tcg2ConfigDxe: Add setup option to configure PPI version

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=288

gEfiSecurityPkgTokenSpaceGuid.PcdTcgPhysicalPresenceInterfaceVer was
introduced to configure physical presence interface version. but test
or user needs to build different images to support different versions
separately as the PCD does not support Dynamic types.

This patch is to extend the PCD to support Dynamic types and add a
setup option in Tcg2ConfigDxe driver to configure the physical
presence interface version, the PCD needs to be DynamicHii type and
maps to the setup option.
