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
.
