Re: [css-houdini-drafts] [css-properties-values-api] Mass property registration (#1058)

The same thing that makes an unregistered property exist for real: specifying it somewhere. E.g. for `#foo { --thing: 1; }`, `--thing` shows up in the gCS enumeration on `<div id=foo>`, but the infinite amount of unregistered custom properties that _could_ have been specified do not.
