* Untangle mutual dependencies between objects and constructor order (OPP-3858): * FWebBrowserWindow no longer keeps a reference to FWebBrowserHandler. * CefBrowserWindow is created before creating FWebBrowserWindow and passed to its constructor. * FWebBrowserViewport no longer has a reference back to the viewport widget. * Cleaned how some platform specific paths were defined during module initialization. * Sets current thread name (back) to GameThread after initializing CEF (UE-5165) * Adopted changes from UT (with some modifications): * Enable on-disk caching and persisting cookies when requested by server. * Added product name and engine version to user agent request header. * Ensure UStruct parameters passed by value to FWebJSFunctions are copied when constructing the argument list and not just their address. *SWebBrowser scripting: Add support for passing TMap<FString, T> to FWebJSFunction objects. Note: since the struct serializer does not yet support maps, this only works for arguments passed directly to the function object and not UStruct members nor function return values. OPP-3861 * Add support for passing a reference to the JS promise object implicitly created when calling UFunctions to provide for a way to report runtime errors back to it instead of just passing the return value. * This also allows for implementing async functionality as the promise object can be saved and used after the UFunction has returned. Merging CL#2633955, CL#2634077, CL#2634226, CL#2635540, CL#2636167, and CL#2636262 using UE4-To-UE4-LauncherDev [CL 2636308 by Keli Hlodversson in Main branch]
