QGraphicsAnchorLayout: prepare ground for doing less simplifications

Add variables to track whether the graph is simplified or not, as well
as make the functions that need it simplified/restored call the
corresponding functions. The functions look at the state variables, so
it's safe to just call them.

Also added Q_ASSERT() through the code paths that SHOULD have the full
graph (not simplified), for making easy to track bugs in future
refactorings.

Ironically this commit cause more calls to simplify/restore right now,
but the state will be better when we fix some functions to be
simplification compatible ;-)
