Vitis Unified remember open files between sessions

[digitalnumeric]

Right now when you close and reopen Vitis you are always presented with a blank slate. It does not remember the files/tabs you had opened previously.

Modern IDEs typically remember the files/tabs from the last session the project was opened.

Update Vitis Unified to remember open files/tabs between sessions so that when reopening a project it automatically opens all the files/tabs that were opened when Vitis was last closed.
