Update ANTLR lexer and grammar #123

This pull request updates the ANTLR files for describing the language grammar. It mainly contains the recent modification in the compiler repository. Some earlier modification to QSharpParser.g4 is also added to keep the consistency between these two repositories.

@samarsha Could you take a quick look at this?

@samarsha Sorry, I did not notice the grammar targets Java. I have updated the lines you mentioned above and generated Java files using ANTLR 4.9.2. VS Code does not report errors regarding the generated files. As a comparison, the original predicate _localctx.terminal.Text did cause an error. Although I did not execute the parser for actually parsing a Q# file, I guess the previous evidence is strong enough.
