#4179: Prevent templates from loading Dashicons library twice

 Some templates load two versions of the dashicons library, which impacts
 performance.

 The homepage, and some other templates (e.g.,
 https://wordpress.org/support/), make a call to //s.w.org/wp-
 includes/css/dashicons.min.css?20181204 in the header.

 Some templates (plugins, themes) enqueue https://wordpress.org/support/wp-
 includes/css/dashicons.min.css?ver=5.2-alpha-44746.

 Some templates load ''both'' versions, e.g.,
 https://wordpress.org/support/

 We should make this consistent, and only load one. I suggest de-enqueing
 the resource everywhere, and leaning on the 'hard-coded' call in the
 homepage/main header file.
