comctl32/button: Use the brush from WM_CTLCOLORSTATIC to fill background for checkboxes and radio buttons. 

Fix radio buttons of Mupen64-RR-Lua input window having stale background. Mupen64-RR-Lua doesn't actually handle
WM_ERASEBKGND even though it returns nonzero. And tests show that a WM_CTLCOLORSTATIC is sent and the returned brush
is used for filling background, even painting over the content from DrawThemeParentBackground().
