Implement `aria-sort` and change icon states to indicate current sort for list tables. Allow screen reader users to get context about the current sort and allow sighted users to know how the table is currently sorted. Props afercia, rianrietveld, joedolson, alexstine, johnjamesjacoby. Fixes #32170. Built from https://develop.svn.wordpress.org/trunk@55971 git-svn-id: http://core.svn.wordpress.org/trunk@55483 1a063a9b-81f0-0310-95a4-ce76da25c4cd
