Investigate onCellAction behavior with selectionMode="replace"

onCellActions behave oddly with selectionMode="replace" (aka highlight selection mode), preventing row selection on click. This is specifically for tables created with the aria hooks, the React Spectrum TableView doesn't support cell actions.

Ideally, onCellAction should behave similarly to onRowAction in selectionMode="replace" (i.e. described here in https://react-spectrum.adobe.com/react-aria/useTable.html#row-actions). May require changes to usePress to continue propagation, try stuff out.

Start with the aria hooks table behavior around onCellAction and selectionMode="replace", then compare it with the onRowAction behavior described in the useTable documentation. Investigate whether usePress is stopping the propagation needed for row selection, and verify that cell actions preserve row selection on click without changing React Spectrum TableView behavior.
