Add RedirectAppLinks component to APM

[smith]

#67595 added the RedirectAppLinks component, which wraps intra-Kibana anchor tags to they redirect properly without causing a full page refresh.

• Add this to APM at the root of the application
• Remove unnecessary navigateToApp usage
• Ensure all intra-Kibana links work without page refreshes where possible
• Ensure all in-app links continue to work as well.

RedirectAppLinks uses the platform history object (passed through in params.history in renderApp's arguments), so we'll need to complete #65682 before this.

We may also need to add an onClick handler to the breadcrumb routes that calls navigateToUrl. (related Slack thread: https://elastic.slack.com/archives/C5TQ33ND8/p1594906008200700)
