Improve aria support - Columns and Navigation Drawer Icons (#2299)

* feat(aria): Add aria-labels to underlabelled tab nav items

The drawer tabs which control primary navigation are only labelled by a title which is not available to many screenreaders. Add an aria-label attribute to each link to improve readability with screenreaders. Organize link attributes so link target is first followed by classname.
Issue #1349

* feat(aria): Replace abstract aria role of section with region

Abstract aria roles such as section should not be used in content. Use non-abstract 'region' aria role instead. That role expects an aria-labelledby attribute with an id. Pass an ID to the column header. Remove the aria-label attribute on the ColumnHeader because the same value is output in plaintext as its child.
Issue #1349

* fix(aria): Remove aria-controls attribute until solution is found

Columns do not have wrappers, so these icons can't point to a column wrapper which it controls. Instead these icons function as triggers to show or hide individual columns.
#1349

* fix(typo): Remove type of aria-labelledby instead of aria-label
