Subject: Allow preventing PrepareStackTraceCallback
Node.js sets a stack trace handler specific to the v8::Context
corresponding to the current Environment. When we're running in a
non-Node.js v8::Context, 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.
