Print encoded errors only if data binding is invoked from the IDE

This CL makes Scope aware of execution environment. Now when invoked
from tests or via IDE, we'll print exceptions as encoded so that we
can parse them back. When user invokes from command line or any other
tool, we will print human readable errors.

The encoded error format may still change depending on conversations
w/ Studio team.
