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.
