MdePkg: Add deprecated warning to BaseRngLibTimer
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4504
To keep the MdePkg self-contained and avoid dependencies on GUIDs
defined in other packages, the BaseRngLibTimer was moved to the
MdePkg.
Add a constructor to warn and request to use the MdeModulePkg
implementation.
