src: allow preventing SetPrepareStackTraceCallback

Node.js sets a stack trace handler specific to the v8::Context
corresponding to the current Environment. When Electron is running in a
non-Node.js v8::Context (e.g in the renderer process with
contextIsolation enabled), there will be no correspondent Environment -
we therefore need to prevent this handler being set so that Blink falls
back to its default handling and displays the correct stacktrace.
