Update overlay attach dynamic component overload

[damyanpetev]

Since the ComponentFactory is deprecated and the new way of creating dynamic components in Angular is done through the viewContainerRef I think we should update our Overlay's attach with an overload that accepts a viewContainerRef. The current overload:

igniteui-angular/projects/igniteui-angular/src/lib/services/overlay/overlay.ts

Lines 321 to 322 in a7aebb0

	public attach(component: Type<any>, settings?: OverlaySettings,
	moduleRef?: Pick<NgModuleRef<any>, 'injector' | 'componentFactoryResolver'>): string;

Should be deprecated - the sooner the better, so we can have a transition period before the old API is dropped.
