Summary:
Tables were using a custom virtualization, which wasn't as performant as other solutions out there. In this diff, the table component is reworked for performance.
- removes `Table` component, because it was never used standalone, `ManagedTable` is what all plugins used
- uses `react-window` for `ManagedTable`
- reworks table highlighting and arrow-navigation to work with the new virtualization
- moves actual filtering out of `ManagedTable` into `Searchable` component for a better separation of concerns.
