PrmPkg: Add PlatformGuid
Adds a "platform GUID" field to the PRM ACPI table. This field
is used by a platform to uniquely identify itself such that it
can be targeted by runtime PRM module updates for that platform.
Platforms using PRM are currently required to set a unique value
for gPrmPkgTokenSpaceGuid.PcdPrmPlatformGuid in their platform
DSC.
