Adjusted expected exception position in ParserTests for bug1532 and removed QuickTime session initialization from bug1532.pde to reflect updated test requirements.
* Move to ANTLR 4 with Java 11 lang features and localization.
Introduces ANTLR4 and Java 8 language feature support within IDE while also adding additional hooks for localization of syntax error messages, addressing https://github.com/processing/processing/issues/3054 and https://github.com/processing/processing/issues/3055.
The PR is broadly a continuation of https://github.com/processing/processing/issues/3055, bringing it up to speed with the latest Processing master plus the changes introduced at https://github.com/processing/processing/pull/5753. **Requires https://github.com/processing/processing/pull/5753 as pre-requisite.** This introduces a number of edits beyond https://github.com/processing/processing/issues/3055 beyond compatibility with current Processing master and https://github.com/processing/processing/pull/5753 including:
- Update to the grammar itself
- Change ANTLR listeners to emit `TextTransform.Edit` to unify JDT-based `PreprocessingService` and `JavaBuild`, removing code with duplicate purpose.
- Introduction of syntax error rewriting with support for localization.
- Addition of complete localized strings set for English and Spanish.
- Addition of partial localized strings set for other languages.
- Refactor of ANTLR-related code for testability and readability
- Expansion of tests including full parse tests for new Java features (type inference, lambdas).
