Add integration test support to GN.

This adds a simple integration test to verify that the GN works
correctly. It is a modified verison of examples/simple_build, with the
following changes:
* Remove any platform-dependent logic, allowing us to use the same
  goldens for all platforms
* Add flags to the toolchain to make it very obvious what flags are
  where, given that the tools are not runnable anyway.

And while I'm at it, attempt to reduce the tech debt of build/gen.py by
creating a simple API for writing the GN ninja file. We can migrate to
it slowly.
