Re-reland: Add MemoryCoordinator

Re-reland: Add MemoryCoordinator

This is second attempt. Hope GYP Mac is happy with this :(

Original description:

This CL adds MemoryCoordinator mojo interface and
its implementation. When --enable-features=MemoryCoordinator
is specified the browser and renderers create their
MemoryCoordinators. MemoryCoordinatorImpl (which lives in
the browser process) creates a mojo message pipe when a
renderer is launched.

This CL doesn't add actual handling of memory events, which
will be implemented in follow-up CLs.

This time I'm trying all *_gyp_* bots on mac. I'll land this if all bots are
happy.

[henrika (OOO until Aug 14), 2016-07-14 11:19:18]

A revert of this CL (patchset #2 id:20001) has been created in
https://codereview.chromium.org/2145403002/ by henrika@chromium.org.

The reason for reverting is: Seems to break building on Windows.
