[edk2] [PATCH v1 06/22] DynamicTablesPkg: Standard NameSpace Objects

The dynamic tables frameworks core communicates with the
platform specific implementation using the configuration
manager protocol interface. The dynamic tables framework
core uses this interface to retrieve information required
for generating the firmware tables. This information is
represented in the form of objects, which are classified
as standard namespace objects, Arm namespace objects or
as Custom/OEM namespace objects.

This patch introduces the definitions for standard
namespace objects.
