Breaking changes in dxc sidenav component

[Tarun-DXC]

Describe the bug

1. arrow that allows the user to hide or show the component on the screen not supported in 3.0.0
2. Modes push and overlay no more supported

To Reproduce
https://codesandbox.io/s/sidenavwithchildren-forked-bcjt6?file=/src/app/app.component.html

Expected behavior
Sidenav should support arrow and modes as mentioned in guideline

Screenshots
If applicable, add screenshots to help explain your problem.

Additional context
There are 2 sidenavs in cdk. One on application-layout component and another standalone sidenav. Both have different APIs. In my opinion a sidenav is a sidenav irrespective of implementation and application-layout should use standalone sidenav component.

@mawelCaballero - This fix you made is for app-layout. The issue I have opened is for dxc-sidenav component.
In my opinion this issue needs to be reopened
