DynamicTablesPkg: Add support for non-serial DBG2 devices

This commit adds support for building non-serial DBG2 devices

1. Add new common namespace objects:
   - EArchCommonObjMemoryRangeDescriptor
   - EArchCommonObjDbg2DeviceInfo

2. Enhance DBG2 table generator:
   - Add support for non-serial DBG2 devices
   - Support multiple debug devices
   - Improve memory handling with proper allocation checks
   - Add better cleanup in error paths

3. Update configuration manager:
   - Add parsers for new common namespace objects
