Summary:
Previously we allow `{[key:string]:Something}` in codegen, `Something` is type-checked but thrown away, generating a `GenericObjectTypeAnnotation`.
In this change, `Something` is added to `GenericObjectTypeAnnotation` as an optional field.
For downstream code such as C++ codegen, this change is **backward compatible**. It allows C++ codegen to produce a more precious type optionally.
## Changelog:
[General] [Added] - Recognize dictionary type in codegen

Summary:
- Add a typescript project to test `CodegenSchema.d.ts`. More tests for other .d.ts files will be added in future pull requests.
- The build script scans all snapshots from `react-native/codegen`'s typescript frontend and generates .ts files for each snapshot, but they are .gitignore-ed.
- `npm run build` will build these .ts files against `CodegenSchema.d.ts` after generating them.
- A failed jest case is included to ensure CI catch it, it will be removed before merged.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/36345
`exactOptionalPropertyTypes` is a TypeScript 4.4+ option set by users which changes behavior of optional properties, to disable accepting explicit `undefined`.
This is not enabled when using `--strict`, and is stricter than Flow, leading to most of the typings having an `| undefined` unique to TypeScript (added with https://github.com/DefinitelyTyped/DefinitelyTyped/commit/694c663a9486dbe7794d5eb894a691ee9ded318a).
We have not always followed this (I have myself previously assumed the two are equivalent). We can enforce that the convention is followed with a plugin `eslint-plugin-redundant-undefined`. This forces us to declare that every optional property accepts an explicit undefined (which Flow would allow). Alternatively, if we do not want to support this, we can enable the existing dtslint rule `no-redundant-undefined`.

Summary:
Add minimum necessary .d.ts files to react-native-codegen.
I found .d.ts files will be copied to `lib` so I guess no additional script is needed.
