Simplify localView

We write a lot of code like this

auto fvGeometry = localView(gridGeometry);
fvGeometry.bind(element);

How about introducing an overload

auto localView(g, element) { auto view = g.localView(); view.bind(element); return view; }

so we can write instead (for most cases)

auto fvGeometry = localView(gridGeometry, element);
