DEV: Standardize table sorting verbiage (#9757)

* DEV: Standardize table sorting verbiage

This commit creates a common component that tables can use to make their
headers sortable. This commit also standardizes on using `desc` as the
default and passing in the `asc=true` flag to adjust the sorting
direction.

* Add deprecation warnings

Adds deprecation warnings if using previous params and maintains
backwards compatibility. Set the default sort value for group members to
be asc.

* switch group requests to use common table-header-toggle

* update fixture
