[chore] Fix requiredBundles for kibanaReact and kibanaUtils

[clintandrewhall]

As titled. kibanaUtils has an unused API and kibanaReact has no plugins. They should be requiredBundles in all instances.

In addition, when starting, Kibana detected plugins that weren't using the bundles at all. Those have been removed.

Nice work! Changes LGTM, did not test locally!

Non blocker: I saw a few example plugins that also need these values updated:

./x-pack/examples/alerting_example/kibana.jsonc
./x-pack/examples/triggers_actions_ui_example/kibana.jsonc
./x-pack/examples/reporting_example/kibana.jsonc
./x-pack/examples/testing_embedded_lens/kibana.jsonc
./x-pack/examples/screenshotting_example/kibana.jsonc
./x-pack/examples/gen_ai_streaming_response_example/kibana.jsonc
./x-pack/examples/third_party_maps_source_example/kibana.jsonc
