[css-text-4] Expand definition of `text-autospace: punctuation`

[fantasai]

Filing this issue to suggest

• Moving the rules for text-autospace: punctuation to an appendix, where they can be more easily updated without overtaking the property definition.
• Adding rules for other languages, e.g. around quotation dash.

If anyone has rules to suggest, or references to rules that we should know about, please comment here. ^_^
