[RTL] ColumnSorting

[Siemienik]

Description

For RTL, the sorting icon should be displayed on the left.

How to reproduce

1. Use this configuration:

{
    data: [
        ['Tesla', 'Model 3', 'BlueStar', 'USA', '★★★★'],
        ['Tesla', 'Model S', 'WhiteStar', 'USA', '★★★★★'],
        ['Mitsubishi', 'iMiEV', '', 'Japan', '★★'],
        ['Ford', 'Focus EV', '', 'USA', '★★'],
        ['Mitsubishi', 'iMiEV Sport', '', 'Japan', '★★'],
        ['Tesla', 'Roadster', 'DarkStar', 'USA', '★★★★★'],
        ['Volkswagen', 'e-Golf','', 'Germany', '★★'],
        ['Volkswagen', 'E-Up!', '', 'Germany', '★★'],
