Component used: Activity Version used: 1.2.0-alpha06

The APIs of LifecycleOwner provide us with a callback for when you reach the CREATED state, but for activities that is often after some critical code needs to run.

For example:

Calling setTheme to reset your theme from a branded launch theme
Calling setLocalNightMode()

These all need to be called before super.onCreate() and specifically the inflation of any layout.

It would be nice if there was a composable way to get a callback at that exact time without needing to manually add code to onCreate() (which, will fine for app code, is hard to do as a library).
