DynamicTablesPkg: Move LPI info object to Arch Common

Browse Source 
Move the LPI info object from Arm Namespace to the
Arch Common namespace.

Correspondingly also update the following modules to reflect the
changes introduced by the move:
 - SSDT Cpu Topology generator
 - ConfigurationManagerObjectParser
 - Dynamic Plat Repo TokenFixer map.
