Missing roles for dt, dl, dd

[JAWS-test]

https://w3c.github.io/html-aria/: dt, dl and dd have "No corresponding role"

But at https://w3c.github.io/html-aam/ they have the roles list, term and definition

There are also issues in html aam about how those aren’t exactly right. I need to tidy it up over there first/or along with whatever is done here.

Also wanted to add current stable versions of Chrome, Firefox, and Safari show term and definition for <dt> and <dd> respectively. <dl> seems to be inconsistent, with Safari showing no role and Chrome/Firefox returning definitionlist which may be a subclass of list? Dunno
