Windows-on-ARM testing fixes

- Blacklist the (recently crashing) GLPrograms unit test

- Only test ANGLE ES3 (not ES2) on our Windows-on-ARM bot

With recent changes, ANGLE always returns an ES3 context. They may
reverse that decision, but at the moment there is no actual difference
so the testing is redundant. For this bot in particular, each config
takes upwards of 20 minutes, so this will significantly speed up one of
our slowest bots.
