feat: merge view+module native templates (#562)

This adds new templates that use `Kotlin` and `Objective-C`. The
templates each have a native view and a native module included.

1. With 993d5cd, the new arch and mixed
arch views will no longer have the `View` suffix in their codegen names.
This doesn't break codegen as the name field is arbitrary as it isn't
stated otherwise [in the new arch working group
documents](https://github.com/reactwg/react-native-new-architecture/blob/main/docs/enable-libraries-prerequisites.md#configure-codegen).
One important matter to remember here is to make sure we pass the `RN`
prefix since headers can conflict.
2. No more Java templates! I've removed them all for the sake of Kotlin.
3. I've removed templates like view-new (new arch-only view template)
since we now have view+module templates and it would be hard to maintain
the old model.
4. I kept `module-legacy`, `module-mixed`, and `module-new` since they
are used by cpp.
5. I kept `module-legacy`, and `view-legacy` since they are used by
Swift.

1. Go to `packages/create-react-native-library`.
7. Call `yarn prepare` to build the CLI.
8. Run `./bin/create-react-native-library` to run the CLI you built.
9. Fill in the name, email, etc., and make sure to select ` Fabric view
and Turbo module with backward compat`.
10. Go to the library you created and make sure to build the following:
    a. Android with old architecture
    b. iOS with old architecture
    c. Android with new architecture
    d. iOS with new architecture
