Add new method `historyGo`, that will let the user navigate to a specific page from session history identified by its relative position to the current page. We add some tests to `location_spec.ts` to validate the behavior of the `historyGo` and `forward` methods. Add more tests for `location_spec` to test `location.historyGo(0)`, `location.historyGo()`, `location.historyGo(100)` and `location.historyGo(-100)`. We also add new tests for `Integration` spec to validate the navigation when we using `location#historyGo`. Update the `historyGo` function docs Note that this was made an optional function in the abstract classes to avoid a breaking change. Because our location classes use `implements PlatformLocation` rather than `extends PlatformLocation`, simply adding a default implementation was not sufficient to make this a non-breaking change. While we could fix the classes internal to Angular, this would still have been a breaking change for any external developers who may have followed our implementations as an example. PR Close #38890
