[Workspaces] Saving app properties on launch and recapture (#36751)

Browse Source 
* [Workspaces] Implementing set and get GUID to/from HWND to distinguish windows moved by the Workspaces tool

* After launch and capture copy the CLI args from the "original" project

* Fix getting GUID

* spell check

* modification to be able to handle different data sizes on different systems

* code optimisation

* Replacing string parameter by InvokePoint

* renaming variable
