Meeting with Fuchsia and Crashpad today to figure out what to do for OS-level crash reporting. Hopefully this can be sorted out in a way that means limited integration work for Chromium (and other applications).

fuchsia: Add dependency on //headless to get headless_shell target

This lets gn generate build files that contain headless_shell as a
target, but there's still lots of porting to be done to get it to
actually build.

Dependencies on crash reporting are excluded, as it is expected
that a shipping product would rely on the Fuchsia system crash
reporter, so Chrome itself does not need a separate one.

Make cast_shell buildable for Fuchsia

1. Added ifdefs around crash-reporting,  bug 753619 .
2. Added CastContentWindowFuchsia.
4. Disabled NetworkChangeNotifierFactoryCast - will need to add a
   Fuchsia-specific implementation once we have an API

This bug was mentioned a bunch in https://chromium-review.googlesource.com/c/chromium/src/+/703876 / https://chromium.googlesource.com/chromium/src/+/6af0b54f5fa9656e42a3fcf252488a927b031ab8 .

There's no crash integration in Chrome-on-Fuchsia, but Crashpad is the system crash reporter on Fuchsia, and it sends data to the (chrome) crash server, so we're pretty close to what we'd need.

Some follow up (possibly server-side?) might be required to be able to cross-reference crashes between platforms, or otherwise slice data to see it in the way we want, as well as on additional features in Crashpad to get more data into dumps.
