Revert "Merge two immersive mode window properties."

This reverts commit 1e9af0714f0e6164ff6d3444bee334c4f2d02778.

Reason for revert: Caused single_process_mash_browser_tests failure

Bug:  900126 

Original change's description:
> Merge two immersive mode window properties.
> 
> aura::client::kImmersiveFullscreenKey is folded into
> ash::kImmersiveIsActive
> 
> No bug here currently, but it's confusing to have two different
> properties that are both meant to indicate immersive mode is active.
> 
> Also removed some unnecessary ash:: prefixes from //ash.
