Clipboard context value for the "evaluate" request

[karthiknadig]

DAP clients (frontends) use the evaluate request when copying variable and expression values to the clipboard. To help debug adapters detect this scenario, a new value clipboard has been added to the value set for the context argument that is passed to the evaluate request. To ensure backward compatibility, a client is only allowed to pass the new value if the debug adapter returns a supportsClipboardContext capability.

Using str(value) in the variable watcher to prevent truncating the copied value is a bit annoying...

Implementing this feature would be much appreciated 😃

As a note, this is already in my short-list of issues TODO, so, it should not take much longer for it to be implemented...
