This will help external projects that want to use Dawn, like Skia, refer
to GN targets without GN discovering Dawn's main BUILD.gn file that
causes all the tests and third_party dependencies to be discovered.
This CL just splits off chunks of BUILD.gn into separate file, adds
necessary includes and fixes up GN paths. It also introduces temporary
groups for targets that are used in Chromium so that the paths can be
fixed in a 3-way patch.
