wxCustomBackgroundWindow is a new class allowing to set a custom bitmap for
the background of any window. The relevant code was mostly moved from wxPanel
to which it was added only recently (before 2.9.2) making it unnecessary to
preserve compatibility.

This ensures that the panel background is used by its transparent children
under wxMSW even when the panel itself is inside a wxNotebook with themed
background: making InheritsBackgroundColour() return true prevents the
notebook from overriding our background.

This method provides a simple way to set a background bitmap without defining
an EVT_ERASE_BACKGROUND handler and, more importantly, one that works
correctly in wxMSW for a window with children as it paints the background of
transparent children too.
Add a test of this method to the erase sample.

So far we have only wxMSW-specific implementation (and also a trivial
wxUniv-specific one) but it's still tidier to have all platform-specific code
in separate files, especially as we're going to have more of it for wxMSW
soon.
