src: expose granular SetIsolateUpForNode

This PR exposes a new embedder-focused API: SetIsolateUpForNode.
It maintains previous behavior for the single-param version of
SetIsolateUpForNode and changes no defaults, but was designed to be
flexible by allowing for embedders to conditionally override all
callbacks and flags set by the previous two-param version of
SetIsolateUpForNode.
