Extract RuntimeEventRouter from extensions Runtime API

Extract RuntimeEventRouter from extensions Runtime API

Another step toward moving the runtime API to src/extensions so it can be
used by app_shell.

yoz, PTAL

This is a mechanical extraction of this class with a little bit of cleanup. Next
is to move the runtime.json file to src/extensions, but that will require
introducing a src/extensions equivalent to Chrome's
extensions_api_resources.h/grd so I'm going to do it in a separate CL.

LGTM
I think you can also remove chrome/browser/extensions/api/runtime_api.cc from
the Android reinclusion list in the gyp file.

You're right!  Done.  Good catch.

A revert of this CL has been created in
https://codereview.chromium.org/213313007/ by jamescook@chromium.org.

The reason for reverting is: After talking to yoz@ and rockot@ I don't
think we want to extract the runtime implementation to src/extensions. It's got
too much Chrome-specific stuff, and for app_shell we really need app_runtime and
not runtime.
