Clean up updating bounds after config/display info change

We always update the display info before handling the configuration
change. Thus, we remove this weird interleaving asynchronous beast
of code and handle rotation and density in updateBoundsAfterConfigChange
and everything else in updateDisplayInfo.

Sending an asynchronous message to resize the stack only causes race
condition and issues.
