[a11y][ViewSettingsDialog]: List group structure results in confusing count info from screen reader announcement

Bug Description

In the ViewSettingsDialog the sort options are structured as 2 separate single select lists, each with only 1 group in it. Our a11y team has reported concerns over the announcement this semantic structure produces. Currently the SR will announce that the lists have 1 item (the group), and then go into further details about the group. Additionally, the "Sort Order" list is announced as "View Settings List" whereas the "Sort By" list is announced as "Contains Selectable Items list". The current structure of 1 group within 1 list results in confusing count information that calls into question ACC-264.

See the SR announcement below:

Affected Component

ViewSettingsDialog

Expected Behaviour

Ideally the Sort By and Sort Order List groups should be individual radio groups. This way the grouping label, correct item count and interaction instructions is clear to screen reader users.
