Move report* callbacks from ANTLRErrorStrategy to ANTLRErrorListener

[sharwell]

The following calls are made from within ParserATNSimulator for reporting purposes only. The results of the call do not have any direct impact on parsing.

• ANTLRErrorStrategy.reportError This one can't be moved. Generated code calls this method and the error strategy determines what/when to report to the listener.
• ANTLRErrorStrategy.reportAmbiguity
• ANTLRErrorStrategy.reportAttemptingFullContext
• ANTLRErrorStrategy.reportContextSensitivity
• ANTLRErrorStrategy.reportInsufficientPredicates

These methods are more appropriate as part of the ANTLRErrorListener interface.

If someone does need an error strategy where behavior is dependent on these callbacks, it would be easy to simply implement both ANTLRErrorStrategy and ANTLRErrorListener on the same object.
