As per planned breaking change to let platforms decide how they and what throw for late initiaization errors, we no longer need a public `LateInitializationError` class. It's confusing to have one if some platforms throw something else instead. Removes the public abstract class. The dart:_internal implementation class `LateError` no longer implements it. This is the only implementation of the public interface, and the class which platforms either throw directly, or through front-end lowering of the feature. Remove mentions in tests. All tests now just expect `Error`, some platform specific tests might test the message. TEST=rewrote tests referring to LateInitializationError.
