Make node-report part of core runtime because:

1. When enabled, node-report significantly helps root cause various
types of problems, including support issues sent to the various repos
of the Node.js organization.

2. The requirement of explicitly adding the dependency to node-report
in user applications often represents a blocker to adoption.

Major deviation from the module version of the node-report is that the
report is generated in JSON format, as opposed to human readable text.

No new functionalities have been added, changes that are required for
melding it as a built-in capability has been affected on the module
version of node-report (https://github.com/nodejs/node-report)

Notable Changes:

* events:
  * For unhandled `error` events with an argument that is not an
    `Error` object, the resulting exeption will have more information
    about the argument.
    #25621
* child_process:
  * When the `maxBuffer` option is passed, `stdout` and `stderr` will
    be truncated rather than unavailable in case of an error.
    #24951
* policy:
  * Experimental support for module integrity checks through a manifest
    file is implemented now.
    #23834
* n-api:
  * The `napi_threadsafe_function` feature is now stable.
    #25556
* report:
  * An experimental diagnostic API for capturing process state is
    available as `process.report` and through command line flags.
    #22712
* tls:
  * `tls.connect()` takes a `timeout` option analogous to the
    `net.connect()` one.
    #25517
* worker:
  * `process.umask()` is available as a read-only function inside Worker
    threads now.
    #25526
  * An `execArgv` option that supports a subset of Node.js command line
    options is supported now.

process.on('somesignal', ...) semantics expect the process to catch the
signal and invoke the associated handler. `setupSignalHandlers` perform
the additional task of preparing the libuv signal handler and associate
it with the event handler. It is possible that by the time this is
setup there could be pre-existing registrations that pre-date this setup
in the boot sequence.

So rearm pre-existing signal event registrations to get upto speed.
