Add wxWebView::SetZoomFactor(float) and GetZoomFactor()

Browse Source 
The new method allows to set the zoom level more precisely than the
existing SetZoom(wxWebViewZoom).

Also improve the webview sample by using radio menu items instead of
check items and manually resetting them.

Closes https://github.com/wxWidgets/wxWidgets/pull/1894

Closes #18769.
