Fix crash when handling WM_PAINT during COM operations
Synchronous expose corrupts painter state if it is done during existing
paint operation, which can happen e.g. when requesting some value from
dumpcpp generated wrapper inside a slot.
Fixed by implementing support for setting asynchronous expose and
doing expose according to the setting in handleWmPaint().
