Revise parser to generate handleLiteralSetOrMap

... and no longer generate handleLiteralSet or handleLiteralMap.
In addition, a new hasSetEntry parameter has been added to the
handleLiteralSetOrMap event generated by the parser to support
existing behavior. Once all listeners have implemented
unified collections and that feature is enabled by default,
the hasSetEntry parameter can be removed.

This is the third of several CLs updating the parser and its listeners
to conform to the unified collection spec:
