[TSVB] Remove font awesome icons from annotations and use EUI instead

[stratoula]

Describe the feature:

TSVB annotations use src/plugins/vis_types/timeseries/public/application/components/icon_select/icon_select.js icons on the icons dropdown which exists on annotations. We should use EUI instead as we do in Lens.

There is also one icon here src/plugins/vis_types/timeseries/public/application/components/vis_editor_visualization.js but it is not visible so

we have 2 options:

1. Remove it (or replace with EUI but it is not visible as I said above)
2. Use the EUI resizable component instead of the custom button

<button
            className="tvbEditorVisualization__draghandle"
            onMouseDown={this.handleMouseDown}
            onMouseUp={this.handleMouseUp}
            onKeyDown={this.onSizeHandleKeyDown}
            aria-label={this.props.intl.formatMessage({
              id: 'visTypeTimeseries.colorRules.adjustChartSizeAriaLabel',
              defaultMessage: 'Press up/down to adjust the chart size',
            })}
          >
            <i className="fa fa-ellipsis-h" />
          </button>

This will enable us to remove the package.json/font-awesome
