DynamicTablesPkg: Add SSDT CMN-600 Table generator

The Generic ACPI for Arm Components 1.0 Platform Design
Document, s2.6.4 "ASL code examples" provides information
to describe an Arm CoreLink CMN-600 Coherent Mesh Network
using an ASL definition block table.

The SSDT CMN-600 Table Generator uses the Configuration
Manager protocol to obtain the following information about
the CMN-600 device on the platform:
 - the PERIPHBASE address location and address range;
 - the ROOTNODEBASE address location;
 - the number of Debug and Trace Controller (DTC)
   and their respective interrupt number;

The CMN-600 mesh is described using the CM_ARM_CMN_600_INFO
and CM_ARM_EXTENDED_INTERRUPT structures in the Configuration
Manager.

The SSDT CMN-600 Table generator:
 - gets the CMN-600 hardware information
   from the configuration manager.
 - uses the AmlLib interfaces to parse the AML
   template BLOB and construct an AML tree.
 - uses the AmlLib to update:
   - the "_UID" value;
   - the address location and range of the PERIPHBASE;
   - the address location of the ROOTNODEBASE;
   - the number of Debug and Trace Controller (DTC)
     and their respective interrupt number;
 - serializes the AML tree to an output buffer.
   This output buffer contains the fixed-up AML code,
   which is then installed as an ACPI SSDT table.
