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.
