Bob Nystrom cf8a477cb7 Support test packages in dartdevk in test.dart.
This allows dartdevk to compile tests that import packages like expect.
There are a few pieces to this:

- Add support to build_pkgs.dart to build the kernel summaries for each
  test package (in addition to the analyzer summaries it already
  builds).

- Plumb that through the dartdevc_test target in the GN build as well.

- While we're at it, use GN to build the ddc_sdk.dill file and have
  test.dart load that one instead of the manually built one from calling
  ./tool/kernel_sdk.dart.

- Add command-line arguments to dartdevk for passing in the path to the
  SDK summary and the other summaries to compile against.

- Fix a little typo in processed_options.dart that was preventing it
  from resolving "package:" URIs.

- In test.dart, when compiling a test, link in the summaries for all of
  the test packages.

At runtime, it still uses the JS for those packages generated from the
old analyzer-based front end since the kernel-based compiler isn't
complete enough to compile any of those packages yet.

With all of this, if I change a test to:

  import "package:expect/expect.dart";

  main() {
    Expect.equals("a", "b");
  }

Then it compiles but fails at runtime. The compiler is completing, but
the generated code has some bugs. I don't know enough to fix them
myself, but here's what I've found out:

- In _libraryToModule(), the Library we get from kernel has a null
  fileUri, so this returns an empty string. That in turn means the
  generated JS tries to use "$" as the module name.

  Using this works around it temporarily:

      if (moduleName.isEmpty) moduleName = library.name;

- In _emitTopLevelNameNoInterop(), it doesn't handle the case where the
  NamedNode is a static method on a class. It just generates the library
  and method name, skipping the class, so "Expect.equals(1, 2)" gets
  compiled to "expect.equals(1, 2)" instead of
  "expect.Expect.equals(1, 2)".
