BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4504 The BaseRngLibTimerLib allows to generate number based on a timer. This mechanism allows to have a basic non-secure implementation for non-production platforms. To bind and identify Random Number Generators implementations with a GUID, an unsafe GUID should be added. This GUID cannot be added to the MdePkg unless it is also added to a specification. To keep the MdePkg self-contained, copy the BaseRngLibTimerLib to the MdeModulePkg. This will allow to define an unsafe Rng GUID in a later patch in the MdeModulePkg. The MdePkg implementation will be removed later. This allows to give some time to platform owners to switch to the MdeModulePkg implementation.
