Introduce StatusBarModule

This CL is the 3rd in the series of CLs which intend to "unbind" StatusBar on TV.
In order to make StatusBar really optional and thus to allow us to unbind it, we also need to make some of the classes that depends on it optional as well. For all these cases we need to move from @Inject-annotated contructors to @Provides annotated methods. For this we are introducing StatusBarModule, as well as StatusBarPhoneDependenciesModule and StatusBarDependenciesModule - these two provide dependecies needed to build StatusBar, but not the StatusBar itself
