joedolson fd17918a8a Administration: Set accessible state for list table headers.
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.
