Leverage the Windows Info Protection APIs to unblock enterprise clipboard contents

We should be able to afford terminal the ability to read clipboard contents as [documented in the Windows Info Protection docs](https://docs.microsoft.com/en-us/previous-versions/windows/desktop/EDP/wip-developer-guide#read-data-from-the-clipboard).

However: we may not want to blindly do so. Terminal should not be able to enter/exit an "enterprise" context, and we have no control over what the application on the receiving end does with the pasted content. We can neither vouch for nor evaluate the veracity of those applications.

Start with the linked Windows Information Protection developer guide, especially its clipboard-reading guidance, and review how Windows Terminal currently handles clipboard access. Done requires an agreed implementation and security policy that addresses enterprise context and the receiving application; the issue does not name an entry point or test.
