DYN-9958 WebView2 Cache Folder Code Review

Based in our last discussion, we don't need a unique path for each WebView2 instance and also we don't need a unique path per each Dynamo instance (in Revit or DynamoSandbox) so with this change we will be using the specific path C:\Users\<user>\AppData\Local\Temp\Dynamo\WebView2 for WebView2 cache folder (for DynamoSandbox and Revit).
