[PATCH 2/9] winemac: Add function macdrv_set_view_superview().

[Ken Thomases]

This allows for nesting views in a hierarchy rather than only ever adding them
as direct subviews of the window content view.  This functionality will be used
in subsequent commits.

This takes over some of the functionality of macdrv_set_view_window_and_frame(),
which will be removed in a subsequent commit.
