Refactor and enhance type hinting across various classes in the Swagger-PHP library

- Updated error handling in TokenScanner to use more descriptive variable names.
- Added return type declarations for methods in Analysis, AbstractAnnotation, Components, Items, License, OpenApi, Operation, Parameter, Response, Schema, Context, Generator, and several processors to improve code clarity and type safety.
- Introduced new PipeOperatorEmulator and VoidCastEmulator classes to support PHP 8.5 features.
- Implemented Pipe binary operator and Void cast node classes to enhance the parser's capabilities.
- Improved array filtering and lambda function type hints for better readability and performance.
- Enhanced the handling of annotations and context in various processors to ensure consistent behavior and reduce potential errors.
