tools/vm/page_owner_sort.c: support sorting by tgid and update documentation
When the "page owner" information is read, the information sorted by TGID is expected. As a result, the following adjustments have been made: 1. Add a new -P option to sort the information of blocks by TGID in ascending order. 2. Adjust the order of member variables in block_list strust to avoid one 4 byte hole. 3. Add -P option explanation in the document.
