More aggressively convert punctuation into fullwidth

[1ec5]

Following up from #3505 (comment) and #3438 (comment), 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.
