Re: [csswg-drafts] [css-text-4] text-spacing needs to handle non-fullwidth punctuation also (#6091)

> We've discussed this at the JLReq TF meeting and developed a [note](https://github.com/w3c/jlreq-d/issues/24) (in Japanese). In sum, when a proportional opening bracket is placed before a fullwidth opening bracket (cl-01 in JLReq), and when a proportional closing bracket is placed after a fullwidth closing bracket or a fullwidth fullstop & comma (cl-02/06/07), the extra space within the fullwidth character should be removed.

JL-TF finally agreed to update jlreq(-d) spacing property document ([one defined using Unicode property](https://github.com/w3c/jlreq/blob/gh-pages/docs/spacing_property/spacing_property.md) is under development), based on above direction. This update will cover all of pairs between non-fullwidth punctuation (like in Latin script, and expanded to whole Unicode) and fullwidth punctuation (defined by EAW is F or W, and which were included in definition of JLreq), as:

* adding corresponding character classes for non-wide width ones over defined classes, A/B/BA - adding Ap or something
* expand existing table for omitting spacing, using newly added character classes, with copying conditions where appopriate
