More aggressively convert punctuation into fullwidth

Nobody has claimed this yet.

Following up from https://github.com/mapbox/mapbox-gl-js/issues/3505#issuecomment-257971452 and https://github.com/mapbox/mapbox-gl-js/pull/3438#issuecomment-259611065, we should replace certain non-CJK punctuation with their fullwidth equivalents more aggressively to avoid rotating them.

For example, `壹貳參(com)` correctly becomes:

```
壹
貳
參
ᴒ͡
ᴑ
ᴟ
͝
```

but `com(壹貳參)` becomes:

```
ᴒ
ᴑ
ᴟ
壹͡
貳
參
︶
```

whereas it should be:

```
ᴒ
ᴑ
ᴟ
︵
壹
貳
參
︶
```

To get this right, we need to split `verticalize_punctuation.lookup` into three lookup tables (`leftBinding`, `leftAndRightBinding`, and `rightBinding`) and consider only the side(s) to which the character is naturally bound. So `(` would be part of `rightBinding` because the character to the right is the only one that determines its ideographic-ness, whereas `@` would be part of `leftAndRightBinding` because either adjacent character can make it non-ideographic.

Start with verticalize_punctuation.lookup and the surrounding verticalization logic. Compare the issue's examples for punctuation beside CJK and non-CJK characters, then verify that the separated binding rules produce the expected fullwidth punctuation and avoid incorrect rotation.
