Ben Clayton affb7a3ab9 dawn_node: Begin working on the CMake rules 
This is enough to compile the interop code. This doesn't do anything as we need to emit the NodeJS module entry point, and actually hook up the interop to the Dawn bindings.
This comes next.

# When upgrading to CMake 3.11 we can remove DAWN_DUMMY_FILE because source-less add_library
# becomes available.
# When upgrading to CMake 3.12 we should add CONFIGURE_DEPENDS to DawnGenerator to rerun CMake in
# case any of the generator files changes. We should also remove the CACHE "" FORCE stuff to
# override options in third_party dependencies. We can also add the HOMEPAGE_URL
# entry to the project `HOMEPAGE_URL "https://dawn.googlesource.com/dawn"`
