[Bug]: DataGrid single-select variant has invisible unnamed radio input in the header row

Current Behavior

Related to #33752, the new issue is that the header radio is now invisible and disabled, which works as a solution for keyboard-only users but not screen reader users. Disabled controls are still accessible, and would need to be visible, have an accName, etc. etc.

Expected Behavior

For single-select, the header radio would need to be entirely not rendered, and (in general, not specifically for single select) should not be made invisible if disabled.
