prefers-reduced-data

Support to be added for the CSS media query prefers-reduced-data. This will detect if the user has set "data saver" or other platform equivalent in their system, and give developers hooks into this user desire when loading or styling a page. This is for users who prefer to use minimal amounts of data on their device, and for developers to adapt to this preference.

Motivation

Client hints and Javascript already have access, let's give it to CSS as well
