Administration: Remove any CSS related to Internet Explorer versions 6 – 10.

In WordPress 3.2 support for IE6 was dropped, IE7 followed a few versions later. With the 4.8 release, WordPress officially ended support for Internet Explorer versions 8, 9, and 10. Yet, we still have shipped CSS for the unsupported IE versions....until now! Goodbye to ie.css and star hacks!

  • Removes ie.css and ie style handle.
  • Removes IE specific class names and any related CSS.
  • Drops support for IE8 and older in wp_customize_support_script().
  • Updates compatibility mode for CSS minification to ie11.

Props ayeshrajans, isabel_brison, afercia, netweb, peterwilsoncc, ocean90.
Fixes #17232, #46015.
