feat(InViewport): Updating WindowRef service with more mock properties and functions

Add common window functions and properties to help when running on server platform. Also created a
new injection token to inject browser window object or WindowRef instance

BREAKING CHANGE: inViewportModule.forRoot function now only accepts a single argument which should
be a reference to window or a mock window implementation
