[PATCH 2/6] wined3d: Minimize device windows on focus loss (v3).

[Stefan Dösinger]

Tests for d3d8 will follow after 107631 has been committed.

v3: Check for D3DCREATE_NOWINDOWCHANGES.

v2: Move to wined3d. The different behavior in d3d9ex was due to a
hidden window and not a difference how d3d9ex handles focus loss. See
patch 7.

Another patch will add an action (resize the window to match the
backbuffer size) on window activation. For this reason the swapchain
helper function is called on both activation and deactivation.
