Guangcong Luo 2d3614f325 Refactor battle.dex out of battle
In most other similar systems, like TeamValidator, we use `thing.dex`
instead of having it extend `ModdedDex`. Battle has always extended
`ModdedDex`, though. This changes Battle to match the others.

This should fix an issue with `Battle.data` not being cached.

This also frees up Battle to extend ObjectReadWriteStream<string> in
a future update.
