[Migrate] Built-in transition with AnimatedContent

[KaustubhPatange]

This uses the new experimental AnimatedContent API instead of modifying modifiers which is what navigator-compose does.

AnimatedContent under the hood uses AnimatedVisibility's enter & exit transition which limits to only fading, sliding & change size. If there is a requirement for rotate animation, then it can't be achieved.

Also providing custom transition by modifying the graphics layer through the Modifier is not possible (which is what they are doing internally) due to the above limitations.

Considering these factors, I'll wait till they become more flexible before merging.
