[csswg-drafts] [css-mixins-1] Return value registration names are inconsistent in 'evaluate a custom function' algorithm (#13769)

anttijk has just created a new issue for https://github.com/w3c/csswg-drafts:

== [css-mixins-1] Return value registration names are inconsistent in 'evaluate a custom function' algorithm ==
> 6. If custom function has a return type, create a custom property registration with the name **"return"** (violating the usual rules for what a registration’s name can be), a syntax of the return type, an inherit flag of "false", and no initial value. Add the registration to registrations.

> 11. For each custom property registration of registrations except the registration with the name **"result"**, set its initial value to the corresponding value in argument styles, set its syntax to the universal syntax definition, and prepend a custom property to body rule with the property name and value in argument styles.

Those should be consistent, likely "result" matching the descriptor name.
