[SPARK-11195][CORE] Use correct classloader for TaskResultGetter
Make sure we are using the context classloader when deserializing failed
TaskResults instead of the Spark classloader.
The issue is that `enqueueFailedTask` was using the incorrect classloader
which results in `ClassNotFoundException`.
Adds a test in TaskResultGetterSuite that compiles a custom exception,
throws it on the executor, and asserts that Spark handles the TaskResult
deserialization instead of returning `UnknownReason`.
See #9367 for previous comments
See SPARK-11195 for a full repro
