feat: implement status bar

[vzhukovs]

Current changes proposal provides an implementation of status bar.

As it shown on the example below:

Docker and Podman status bar items displayed as an example.

To use the following API there is an code example provided below:

import * as extensionApi from '@tmpwip/extension-api';
...
const sbItem = extensionApi.window.createStatusBarItem(
  extensionApi.StatusBarAlignLeft,
  extensionApi.StatusBarItemDefaultPriority,
);
//const sbItem = extensionApi.window.createStatusBarItem();
//const sbItem = extensionApi.window.createStatusBarItem(
//  extensionApi.StatusBarAlignLeft,
//);
sbItem.text = 'Podman';
sbItem.iconClass = { active: 'fa fa-toggle-on', inactive: 'fa fa-toggle-off' };
//sbItem.iconClass = 'fa fa-toggle-on';
sbItem.tooltip = 'Podman Engine';
sbItem.command = 'commandId';
sbItem.commandArgs = ['arg1', 'arg2'];
sbItem.enabled = true;
sbItem.show();

By default, help icon moved from the title bar to the status bar and displayed to the right.

fixes #263
