Subject: Supply ExecCtx to op used in with_* and try_with_* functions

With an upcoming change we will require an ExecCtx in one of the
op functions passed to the with_* and try_with_* functionality. To
allow for such cases, this change adjusts the signature of those
functions to provide a reference to such a context.
