mb/google: order matters in mem_parts_used.txt

* Add comments to mem_parts_used.txt to point out that the order of
the entries matters when assigning IDs, so always add a new part
to the end of the file.
* Update existing mem_parts_used.txt to add the same comment.
* No updates to Zork variants, because they use an optional ID, so
the order actually doesn't matter there.

BUG=b:175898902
TEST=create a new variant of dalboz, trembyle, volteer, waddledee,
or waddledoo, and observe that mem_parts_used.txt has the new
verbiage.
