For safe area insets (cutout) support, CSS Round Display Level 1 (https://drafts.csswg.org/css-round-display/#viewport-fit-descriptor) has new viewport value as `viewport-fit`. To support safe area insets that is notch on display, CSS Environment Variables Module Level 1 (https://drafts.csswg.org/css-env-1/#safe-area-insets) adds `safearea-insets-*` (left, top, right and bottom). Also, `meta` element has `viewport-fit` enum value. (ex `<meta name="viewport" content="viewport-fit=cover>`) whether web browser window cover notch area. `viewport-fit` has 3 enum value, `auto`, `cover` and `contain`. GeckoView wants to expose this value to browser application such Fenix. Because Android API (https://developer.android.com/guide/topics/display-cutout) uses window root layout (It is set by Application) to cover notch on display.
