This officially removes support for Internet Explorer 11 in the CSS files run through the build process in Core.
Individual tickets should be opened for removing each manually maintained area of the code base targeting IE11.
The resulting changes to CSS files are included in this commit.

This ensures that contrast between text color and background meets the WCAG 2.0 AA recommended value. The following locations were changed:
- Network List Tables: Use lighter background colors for site status indicator.
- Nav Menus: Use a lighter background color for invalid menu items.
- Pointers: Use a darker background for pointer header.
- Themes: Use darker background on filter button hover.
- Customizer: Use darker background for selected widget.

This is part of a larger project in cleaning up core's admin CSS. This collapses all colors used in the CSS to one of 12 blues, greens, reds, and yellows, 13 grays, pure black, and pure white. The colors are perceptually uniform from light to dark, half of each range has a 4.5 or higher contrast against white, the other half has a 4.5 or higher contrast against black.
Standardizing on this set of colors will help contributors make consistent, accessible design decisions. The full color palette can be seen here: https://codepen.io/ryelle/full/WNGVEjw

WordPress no longer supports many old old browsers: https://make.wordpress.org/core/2017/04/23/target-browser-coverage/
This also removes alot of no longer necessary CSS. It served us well, but we are never getting back together with IE8,9,10.
So, in the (paraphrased) words of Taylor Swift:
I remember when we dropped support the first time
Saying, "This is it, I've had enough, " 'cause like
We hadn't seen many users in a month
When you said you needed flexbox. (What?)
Then you postMessage again and say
"IE8, I miss you and I swear I'm gonna change, trust me."
Remember how that lasted for a day?
I say, "I hate the box model, " we break up, you call me, "I love css-grids."
Ooh, we called it off again last night
But ooh, this time I'm telling you, I'm telling you
We are never ever ever supporting IE 8,9,10,
We are never ever ever supporting IE 8,9,10,
You go talk to EDGE, talk to my FIREFOX, talk to CHROME
But we are never ever ever ever getting back together
Like, ever...

Links used as UI controls that behave like buttons, should be buttons.
- changes the widgets "toggle", "Delete", and "Close" links to buttons
- uses `aria-expanded` to announce the state of the toggle buttons
- increases a bit the clickable area of the toggle
- ensures the "circular focus" doesn't get cut-off in some browsers by centering the toggle arrows
- uses a `<span>` element with an `aria-hidden` attribute to hide CSS generated font icons from assistive technologies
- standardizes on `.toggle-indicator:before` rather than `:after`
- changes two `#f00` reds in `#dc3232`, see #35622Fixes#31476.

For accessibility, UI controls should preferably be native controls. Adds
ARIA attributes and labels to improve accessibility and pair these buttons
with the ones in the Menu Customizer.

* Re-work how and when widget forms get updated.
* Replace ad hoc hooks system with jQuery events,
* Add `widget-updated`/`widget-synced` events for widget soft/hard updates.
* Enter into a non-live form update mode, where the Apply button is restored when a sanitized form does not have the same fields as currently in the form, and so the fields cannot be easily updated to their sanitized values without doing a complete form replacement. Also restores live update mode if sanitized fields are aligned with the existing fields again.
Note: jQuery events are *not* final yet, see #19675.

* Support widgets which are higher than browsers viewport.
* Use widgets width as max-width.
* Don't animate the width of wide widgets to make them visible, instead fade them in/out.
* Fix Chrome flickerings while updating wide widgets.
