David A. Kennedy fa4cbf29f1 Twenty Seventeen: Fix badly pixelated images on iOS devices
The CSS property `background-attachment: fixed` is disabled in some mobile browsers for performance reasons. So here, the fix increases the breakpoint where the `background-attachment: fixed` is applied to the front page images. Doing this removes the fixed backgrounds and the issue from all smaller screens, but the downside is that it also removes the fixed backgrounds from smaller laptops. It's also possible future devices could fall into this breakpoint, but this seems to be the most practical solution.

Props laurelfulford.

David A. Kennedy 4c5f80c839 Twenty Seventeen: Fix playlists not rendering on blog/archive pages when using video or audio post format
TwentySeventeen attempts to highlight media found in post content by using `get_media_embedded_in_content()` to extract videos from the content and display their HTML differently. However, the HTML being generated by the playlist shortcode relies on JavaScript to update the video element with the markup needed to display the playlist properly. The `get_media_embedded_in_content()` function wasn't designed to handle this use case.

The patch looks for the presence of `wp-playlist-script` in the content and shows the standard content rather than trying to pluck the media elements from the content using `get_media_embedded_in_content()`.

David A. Kennedy 495b2d835f Twenty Seventeen: Make sure skip link works in all versions of Internet Explorer
This also reduces the number of browsers detected and patched with this fix. Most modern browsers have patched this common bug, where an anchor link does not move focus when clicked. Twenty Seventeen will only worry about older versions of Internet Explorer in this regard.

Props afercia, sami.keijonen.

David A. Kennedy 0a3d034962 Twenty Seventeen: Correct issues with hidden overflow and height on site header
In -r39124, some additional issues were introduced:

* The 'overflow: hidden' on the `.site-header;` was added to prevent a side-scrolling issue, but it ended up cutting off the menu. It looks like the cause of the side-scroll was related to how the scroll down icon was rotated, so it's addressed by rotating the icon and not the `<a>`.
* Also, `min-height` doesn't play well with `display: table;` in Firefox. So it's addressed with just `height`.

Props laurelfulford, sami.keijonen.

Joe McGill 50b2c6cf2c Customize: Remove Vimeo reference from description for external header videos.
Vimeo's API requires a Pro account to display videos as background videos
(i.e., without player controls), thus we shouldn't support Vimeo
URLs by default in custom header videos. This removes the reference of Vimeo
from the control description in the customizer.

Fixes #38544.
