Replace the hard-coded blocklist ("Response.body" and "Request.body") in
the V8 inspector with proper side-effect free debug evaluate. This is
otherwise a non-functional change and in particular preserves the
behavior of reporting accessors as (own) data properties. That will be
tackled in a follow-up CL.

This CL is possible because with https://crrev.com/c/3056879 Blink now
properly marks accessors as side-effect free consistently with what the
V8 inspector had done before.
