Update CI jobs (#565)

This updates our config to run the following jobs:
* JDK 11 on all platforms, using the latest supported Error Prone version (currently 2.10.0).  This builds and tests all of our targets.
* A "legacy" job, running on Linux with JDK 8 and the oldest supported Error Prone version (currently 2.4.0).  Some targets are now disabled here, like building of sample Android apps and corresponding tests.
* JDK 11 on Linux using the oldest supported EP version, mirroring an internal configuration.
* A JDK 17 job with latest Error Prone that runs core NullAway tests, but still doesn't run all Android / JarInfer tests (still work to do to get them passing).
