refactor: use OpenAPI file path for generator instead of stdin & modernize generator-cli

[Lodin]

This pull request includes significant updates to both the Java and TypeScript codebases, focusing on improving the GeneratorProcessor and GeneratorIO functionalities. The most important changes include the use of direct read of an OpenAPI file instead of copying it to stdin, refactoring the TypeScript generator CLI to use URLs, and updating the test suite to reflect these changes.

Java Changes:

• GeneratorProcessor Enhancements:
  • Used a OpenAPI file name path as an CLI argument instead of copying it to stdin. (packages/java/engine-core/src/main/java/com/vaadin/hilla/engine/GeneratorProcessor.java)

TypeScript Changes:

• GeneratorIO Refactoring:

  • Updated GeneratorIO to use URL instead of string paths for file operations. (packages/ts/generator-cli/src/GeneratorIO.ts) [1] [2]

• CLI Improvements:

  • Refactored the CLI to use parseArgs for argument parsing and removed meow. (packages/ts/generator-cli/src/index.ts)
  • Removed the processInput utility function and updated the CLI to accept the input file path to read it directly. (packages/ts/generator-cli/src/index.ts)

• Testing Enhancements:

  • Updated tests to reflect changes in GeneratorIO and added new tests for the CLI. (packages/ts/generator-cli/test/GeneratorIO.spec.ts, packages/ts/generator-cli/test/cli.spec.ts) [1] [2]
  • Added a new test plugin for better test coverage. (packages/ts/generator-cli/test/TestPlugin.ts)
