refacto(bindgen): remove deprecated typescript_v2

[glihm]

Summary by CodeRabbit

• Refactor

  • Simplified binding generation by removing the legacy TypeScript v2 target, unifying support under the standard TypeScript option.

• Chores

  • Removed the corresponding CLI flag and any configuration paths related to TypeScript v2.
  • Eliminated the deprecated TypeScript v2 plugin and its references across the build and generation flow.

• User Impact

  • The “TypeScript v2” binding target is no longer available. Use the standard “TypeScript” target for code generation.

Ohayo, sensei!

Walkthrough

Removed TypeScript V2 support across CLI and bindgen. Deleted the TypeScript V2 plugin module, removed its enum variants, module exports, CLI flags/args, and plugin wiring. Remaining TypeScript flow now routes solely through the existing Typescript plugin.
