1. Set the EFI_DEBUG_IMAGE_INFO_TABLE_MODIFIED bit on insertion/deletion of entries in DebugImageInfo Table. 

2. Change field EFI_DEBUG_IMAGE_INFO_TABLE_HEADER.TableSize to be the number of valid entries. Apply another global variable mMaxTableEntries to track the maximum of the allocated entires.
