feat: debug with selector option added

[Bayheck]

Purpose

The purpose of this PR is to allow passing selector to a t.debug call. Something like this t.debug(Selector). Then the selector will be shown in debug mode and highlighted.

Approach

So overall, the main goal was to pass the selector argument from server-side debug call to client-side selector-input-contaner.

1. src/test-run/index.ts Inside this file we have _internalExecuteCommand method. There is debug command type handling block. Inside of it we call _enqueueSetBreakpointCommand to which we pass command.selector as a second argument. This way we transfer Selector from debugCommand to breakpointCommand.
2. After the breakpointCommand is added to driverTaskQueue we can work with it on client-side.
3. On client-side we pass selector to _debugSelector method of SelectorInputContainer class.
4. In _debugSelector method we:
   - remove any previously highlighted elements,
   - get Selector name and assign it to this.value for SelectorInputContainer,
   - execute Selector to get elements for highlighting and indication,
   - highlight and indicate elements of the Selector
