Re: [css-houdini-drafts] [css-properties-values-api] `@property` descriptors should be optional whenever possible (#1162)

My reason for combining both topics in one issue is that I’d be fine with requiring some or all descriptors to be set explicitly for the _final_ registration of a custom property to take effect, but I believe that in each individual ruleset every declaration should be optional. It follows naturally that later definitions only overwrite the values of descriptors they set explicitly.
