This ensures that a standard header is shown on the front page whenever
a header video is set without a header image if the video doesn't load,
e.g., on mobile sizes or if the JS doesn't fire.
This adds a new class, `.has-header-video` that is added whenever the
`wp-custom-header-video-loaded` event is fired, which is then used to style
the custom headers along with `.has-header-image` whenever a header image
is available. This also changes the class name on the custom header media
wrapping `div` from `.custom-header-image` to `.custom-header-media`.

iOS disables this feature under the hood, but it also distorts the images – unlike other mobile devices that don't support it. So this adds a check for both `background-attachment: fixed` support or whether it’s an iOS device - passing it adds the class `background-fixed` which is used to add the proper styles.
It also lowers the media query so the parallax-like style is present on a wider range of screens since this bug can be better targeted and avoided. In this way, screens that aren't the offending devices aren't punished merely based on screen size.

* Relies on header skip link instead of l10n variables in JavaScript.
* Fixes issue where scroll down arrow appeared next to the navigation on the front page with no header image or video. It now only appears with a big header.
