[vm/concurrency] Share program structure and JITed code with --enable-isolate-groups

This removes our temporary scaffolding support for JIT isolate groups
(which was implemented by creating a new isolate group, loading the
application kernel into it and then merging the heap into the original
isolate group - maintaining a different object store)

It makes all isolates within a group share the same object store, same
libraries and JITed code. It will be conservative to start with, only
allow running unoptimized code, etc.

We will gradually remove the restrictions imposed by this CL:

Issue https://github.com/dart-lang/sdk/issues/36097

TEST=Tests using --enable-isolate-groups with JIT sharing.
