Row DOM Performance: various keyboard shortcuts don't work

From Amy Li

The datagrid keyboard command Ctrl+End on windows and ctrl+fn+right arrow on mac no longer goes to the last cell of the last row. People who use keyboard-only will not be able to get past the table unless they tab the checkbox controls on every row. This is an issue as there can be thousands of rows with checkboxes to tab through.

@steve-haar In order to determine a11y priority, it will depend on if there is a pagination option a user can enable. If there is no pagination option this will have to be a P0, if there is a pagination option that is default and always available to the user enable (not after the datagrid) then this is a p3.
