chore(amplify-util-uibuilder): remove codegen-ui usage

[Jshhhh]

Description of changes

Removes codegen-ui dependency from CLI. This doesn't change current behavior for ui component generation. The codegen-ui dependency is not needed anymore due to component codegen service.

• copies over necessary helper functions/utils from codegen-ui package

Description of how you validated changes

1. yarn setup-dev
2. Ran amplify-dev pull in a test app with datastore, and another app with graphql
3. Verified that ui components are generated for each app
