AppVeyor: Run tests as part of AppVeyor builds

This includes a bunch of related changes:

- `slang-test`
  - Add a notion of an "output mode" that specifies whether we output to console (the default), or invoke the apprpriate AppVeyor command to update test status
  - Add a notion of test categories, so that tests can be tagged with categories, and then we can invoke only those tets in a given category, or choose to *exclude* tests with specific categories
  - Allow the `OSProcessSpawner` to look up an executable by "path" (meaning a full path is expected) or by "name" (meaning it should be allowed to look in the current directory, `PATH` environment variable, etc.). This was important to make sure that I can run `appveyor` without having to know its absolute path.

- AppVeyor configuration
  - Change badge to reflect new build account for organization (rather than a single-user account)
  - Remove attempt to set AppVeyor build version in a clever way, since it breaks links from GitHub to AppVeyor
  - Change order or configurations in the build matrix to front-load the Release build (which has the main tests)
  - Turn on `fast_finish` flag so we don't have to wait as long for failed builds
  - Turn on `parallel` builds
  - Set `verbosity: minimal` to avoid getting build spew about Xamarin stuff I'm not using
  - Add custom `test_script` to invoke `test.bat`
    - Sets the test category based on teh build configuration, so we don't run the full test suite on every input.

- `test.bat`
  - Allow for `-platform` and `-configuration` arguments
  - Rewrute a platform of `Win32` over to `x86` to match how the output directories are named
  - Futz around with how the directories are being passed along to work around annoying `.bat` file quoting behavior (I still don't get how batch files work)

- Tests
  - Mark a bunch of tests as `smoke` tests
  - Mark the relevant tests as `render` tests
    (these get filtered out for AppVeyor builds)
