add new extension LibraryViewExtension (based on Microsoft WPF.WebView)

[mjkkirschner]

Purpose

replaces #10222

This PR differs in a few way:

• adds a new extension instead of modifying the existing one
• this one builds!
• links some static resource files from existing LibraryViewExtension but embeds them into new dll.
• duplicates most files from LibraryViewExtension - but adds a new namespace - Dynamo.LibraryViewExtensionMSWebView to avoid conflicts between them incase somehow these dlls are loaded at the same time by accident.

here is what I know we need to do (not all of this will be done in this PR)

• make startup faster
• hide the webView when startup page is visible - this is called the airGap problem if anyone is interested: WPF and Win32 interop: 'Airspace' issue dotnet/wpf#152
• There are no tests for this implementation.
• clean up code.... 🔨
• eventually refactor out a common core of types from libraryJS and this extension to share. (longterm)
• add a new .sln for this project (TBD)
• determine how to get this signed with BRE's help or CI library and delivered to artifactory/nuget
• this project should include a readme describing how to integrate this extension and replace the existing library.

unfortunately it looks like while this works okay in DynamoSandbox, it does not work in more complex hosts - which makes it rather useless - I will send a PR soon for a WebBrowser (IE 11 rather than Edge) based version for feedback asap.
