tools/vm/page_owner_sort: support for sorting by task command name
When viewing page owner information, we may also need to the block to be
sorted by task command name. Therefore, the following adjustments are
made:
1. Add a member variable to record task command name of block.
2. Add a new -n option to sort the information of blocks by task command
name.
3. Add -n option explanation in the document.
