We define `sym2.game_add`, which is a relation `sym2 α → sym2 α → Prop` which expresses that one pair may be obtained from the other by decreasing either entry. We add a basic API, and prove well-foundedness.

Pair: leanprover-community/mathlib4#2532

Can we please have the links to the port status dashboard, to make it easier to review the mathlib3 changes?

Arguably it's better not to have these; my intent was for the CI run to generate these links for you, which also means you don't have to trust the author actually pasted the right links.

Unfortunately that CI script seems to be a bit buggy right now, and it would probably be better if it actually made a real PR comment rather than annotations (which are limited to 10 and aren't hyperlinked) and a CI log (which no one knows to look for)
