src: do not use soon-to-be-deprecated V8 API

V8 announced deprecation of the following methods:
 - v8::Object::SetAccessor(...) in favor of
   v8::Object::SetNativeDataProperty(...),
 - v8::ObjectTemplate::SetNativeDataProperty(...) with AccessControl
   parameter in favor of
   v8::ObjectTemplate::SetNativeDataProperty(...) without AccessControl
   parameter.

See https://crrev.com/c/5006387.

This slightly changes behavior of the following properties:
 - process.debugPort (for worker processes),
 - process.title (for worker processes),
 - process.ppid.

The difference is that they will now behave like a regular writable
JavaScript data properties - in case setter callback is not provided
they will be be reconfigured from a native data property (the one
that calls C++ callbacks upon get/set operations) to a real data
property (so subsequent reads will no longer trigger C++ getter
callbacks).
