Reorganize GitHub Actions configuration [skip travis][skip appveyor]

* Skip if commit message contains `ci skip`, `skip ci`, or `skip gha`
  ENCLOSED WITH BRACKETS (excluding lint job).
* Separate build and test. This is because builds can be run in parallel,
  but running tests in parallel can cause logs to get mixed up or not
  finished.
* Don't use Chocolatey because it seems to take 1-2 minutes to start up.
* Use the cache better.
* Use `actions/checkout@v2` instead of `actions/checkout@v1`.
* Remove unnecessary package installation.
* Remove unnecessary flag settings.
* Remove `-j` for rake because it doesn't seem to have any effect.
* Rename `main.yml` to `oss-fuzz.yml` to clarify.
