feat: Add will-resize event to TopLevelWindow (#13649)
The new `will-resize` event can be used to prevent the resize from happening before the native window is actually resized. This is in contrast to the existing the `resize` event, which is sent *after* the native window has already been resized. For apps with e.g. custom window snapping logic, the `resize` event is not sufficient because it will result in flickering between the dragged size and the snapped size. `will-resize` is only emitted on macOS and Windows.
