Jacques Lucke d81ba55ce4 Fix #124467: lazy-connect does not work with Capture Attribute node
The lazy-connect feature of node wrangler uses the built-in `connect_sockets`
function which automatically handles virtual sockets in group input and output
nodes already. However, it does not handle virtual sockets in other nodes.

The fix is to generalize this behavior. For that, a new `handle_dynamic_sockets`
boolean input is added to `tree.links.new`. When enabled, virtual sockets are
handled properly by internally calling the `bNodeType.insert_link` methods.

The new behavior is turned of by default for compatibility reasons.
