Move LaunchManager's two functions to launch utils:
GetLaunchFilesFromCommandLine
CreateNewTabBrowser

Follow up:
1. Move ExtensionAppLaunchManager's function to extensions, and remove
ExtensionAppLaunchManager
2. Modify web_app::WebAppLaunchManager to remove the dependency on
LaunchManager.
3. Remove LaunchManager.
