New Windows clipboard API?

[dacap]

Follow the discussion from: microsoft/WindowsAppSDK#374

There are some interesting points as the possibility to hide the clipboard data from uploading the content to the cloud/history: https://docs.microsoft.com/en-us/windows/win32/dataxchg/clipboard-formats#cloud-clipboard-and-clipboard-history-formats
I think we should expose some API to offer this possibility.
