Don't load wp4.css on the homepage.

[dufresnesteven]

This is an experiment/proof of concept.

WP4.css contains styles that are consistently overwritten in each theme because they are generic and most likely out of date.

While it may seem daunting to pull it out, I think we can de-risk the task by excluding it from each theme (or page) one by one, starting with the homepage. We could then control the damage as we go and at some point we'll be ready to pull the trigger on killing it for good (even if we get 10 new, most likely trivial bugs, in the door as a result) .

There's some functionality on WordPress.org to do just that.

If a WordPress.org theme (or page I guess) registers support for wp4-styles then the global header won't output wp4.css:

themes/pub/wporg-themes/functions.php:	add_theme_support( 'wp4-styles' );
themes/pub/wporg/functions.php:		add_theme_support( 'wp4-styles' );
themes/pub/wporg-plugins/functions.php:	add_theme_support( 'wp4-styles' );

That'll also disable Open Sans and Dashicon loading too, so it's assumed the theme handles fonts.

If I’m remembering correctly some of this work was performed by @obenland as part of #1015, which might also be helpful for reference @dufresnesteven

Perfect. Thanks.

This diff updates wporg-main to include some wp4.css styles so we can exclude it.

Update the mobile layout to match wporg-main.

Add styles to hide download-mobile buttons. We need to move over meta data next.
