Previously we wrapped the embedder entry point callback into a binding and then invoke the binding from JS land which was a bit convoluted. Now we just call it directly from C++. The main scripts that needed to tail call the embedder callback now return the arguments in an array so that the C++ land can extract the arguments and pass them to the callback. We also set PauseOnNextJavascriptStatement() for --inspect-brk and mark the bootstrap complete milestone directly in C++ for these execution modes.

I think this can still be marked in JS with markBootstrapComplete, similar to other entry points.

The other entry points don't take callbacks. I think it's less convoluted to mark this right before we invoke the callback, otherwise it's quite difficult to wrap your head around things going back and forth between C++ and JS for these entry points that take callbacks (that's what I feel whenever I looked at these two, and I even reviewed the original changes).
