Remove "reset" and "document" as valid zoom values (deprecated)

There are two special values for the CSS zoom property that are inconsistently documented: "reset" and "document". They set the element's zoom to 1.0 regardless of parent element zoom status and prevent page zoom from affecting the element's size. We're removing them.

Comments

The zoom proposal draft completely elides "reset" and "document". The values have low usage and behave in unexpected ways. Edge's number's corroborate low usage. Supporting the ability to effectively disable page zoom is user-hostile.
