feat(table): Add interactionMode property to control focus behavior (…

…#8686)

**Related Issue:** #8659 

## Summary
- Adds an `interactionMode` property with `static` and `interactive`
(default) values to Table to allow the table to be used without cell +
header focus.
- When set, prevents keyboard navigation with arrow / home / page keys.
- Still allows focus and tab / shift tab for `interactionMode` selection
affordances in cell + header.
- Still allows tab to / shift tab to reach focusable content
- Prevent focus of "unused" `interactionMode` footer cell in `static`
mode.
- Adds test to check that only interactionMode cells + header are
focused in `static` mode.
- Does not change the default behavior.
