Fixes for layout modifiers

The manner in which LayoutNode reads density from the currently
connected owner is too lazy when it comes to modifier wrapper chain
construction. Always delegate to the LayoutNode rather than capture
eagerly.

Add constraints to LayoutModifier.modifySize so that they can be applied
at each modifier phase.

Change LayoutModifier.modifyPosition to accept the proposed position
and return the new one rather than returning an offset for consistency
with other LayoutModifier methods and added flexibility.

Fix AbsolutePadding modifier behavior when insufficient space is
available and when intrinsic measurements are queried.
