Fixing broken shade after unfolding during expanding QS

The goal of this change is to transmit `QuickSettingsController#computeExpansionFraction() > 0` to CentralSurfacesImpl so in this case we can also close QS before turning screen off.
Now CentralSurfacesImpl checks for shade being fully open or shade being in process of opening/collapsing

In the meantime I noticed mIsExpanding really means mIsExpandingOrCollapsing and renamed it like so - that's why so many files are modified.
Also changed isExpanding() function to be more comprehensive and properly handle shade opening on lockscreen.
