feat: cumulative codegen structure (#14296)

* feat: add codegen auth v1

* chore: add a new tsconfig file for codegen tool

* chore: added codegen tsconfig reference in base tsconfig

* chore: add build artifacts

* feat: add comprehensive codegen tool for amplify gen 1 to gen 2 migration

- add auth generator file to generate typescript asts
- add preliminary unit tests for the auth generator
- integrate the rest of the old migration tool to maintain dependencies

* chore: updated dependencies

* chore: update dependencies

* fix: add proper exclusions for codegen tsconfig

* feat: configure separate TypeScript compilation for gen2-migration codegen

- Add dual build process: main project with strict:true, gen2-migration with strict:false
- Update build script to compile both tsconfigs sequentially
- Exclude gen2-migration directory from main tsconfig to prevent double compilation
- Create separate Jest config for gen2-migration tests with relaxed TypeScript settings
- Update test script to run both Jest configurations
- Add gen2-migration lib directory to .gitignore to exclude compiled artifacts
- Configure gen2-migration tsconfig with strict:false, skipLibCheck, and proper paths

This allows the gen2-migration codegen to build and test with relaxed TypeScript
settings while maintaining strict type checking for the main codebase.

* chore: change auth generator to the original tool

* chore: update jest.config.js

* chore: update jest.config.js

* feat: auth generator update v1

* chore: add separate command for running codegen tests

* fix: revert tsconfig and package.json changes and set strict:false for amplify-cli

* chore: update auth generator to original tool's code
