[DevTools] Support CSS media feature emulation in CDP

This patch makes the pre-existing `Emulation.setEmulatedMedia` API in
the Chrome DevTools Protocol support emulating CSS media features, in
addition to CSS media types (which it already supported).

The new functionality can be used to emulate `prefers-color-scheme`
(light/dark mode), `prefers-reduced-motion`, and any other media
features Chrome implements from now on.
