Add views::View::set_preferred_size, use it in a few places.
This sets a preferred size which will override the one provided by the
layout manager or a subclass's GetPreferredSize override. It also
renames the override-able function to CalculatePreferredSize and makes
it protected. Eventually all GetPreferredSize overrides should be
renamed.
This patch also gives precedence to LayoutManager::GetPreferredSize
over View::CalculatePreferredSize, although this distinction probably
rarely crops up.
