fix: lazy-load repl to avoid domain side effects

Actually starting the repl will still put the process into domain-mode,
but this at least allows programs to use `ts-node` or
`--loader=ts-node/esm` without losing the ability to use
process.setUncaughtExceptionCaptureCallback().

The problem should ideally be fixed (or mitigated) in node core, but
this is still worthwhile for the benefit of supporting current node
versions.
