Android: Default no longer builds generated files

* Switch Android Studio's generate_gradle.py script to no longer build
  all the generated files by default. This reduces runtime for a clean
  build from 10 minutes to 20 seconds. Add a `--full` flag to explicitly
  build these generated files, which should not be necessary on a
  regular basis.

* Most of the benefit from generated files being present is fewer red
  underlines in Android Studio. Many red underlines are from lacking a
  R.java file, which takes a long time to generate.

* Fix bug so generate_gradle.py works even right after `gn clean`.

* Allow users to specify `-j` so generate_gradle.py works without goma.

* Speed up generating the `all` module (which is the default) by not
  creating each sub-project's build.gradle file when generating the
  information that it needs.
