Make isolate.h usable without objects-inl.h header.

Make isolate.h usable without objects-inl.h header.

This CL us a pure refactoring that makes an empty compilation unit
including just "isolate.h" or "contexts.h" but not "objects-inl.h"
compile without warnings or errors. This is needed to further reduce
the header dependency tangle.

Benedikt: PTAL.
Igor: Please provide "ic" OWNER review.

Also, I am looking for a "regexp" OWNER that is _not_ on vacation right now. :(

Hm, wait I think I mentioned that this "process thing" will cause exactly these
kinds of problems, yeah I'm pretty sure I did. I guess there is only one word to
describe the outcome: "Haha!" (Nelson)

But besides that, LGTM from my side
