[Layout API] Use ownerLayoutItem() in LayoutView (part 2)

[Layout API] Use ownerLayoutItem() in LayoutView (part 2)

Direct access to LayoutPart is deprecated and being removed soon. The
replacement is LayoutPartItem, which routes methods through the new
block layout API. (See linked crbug for details.) This means the
ownerLayoutObject() method is also deprecated, to be replaced with
ownerLayoutItem().

There are no functional changes, although I did need to add two methods
to LayoutBoxItem.
