Create script to convert existing components to SDC components

Problem/Motivation

There are a number of changes in CivicTheme 1.11.

We are converting to use SDC which requires an update in build tools and storybook to support SDC and bundling CSS and JS with each component.

We require an automatic script to do a lot of the boilerplate code required for the change. The script should include:

- Update to build systems for CSS compilation
- LLM API script to assist with creating component YML files

The LLM script should use CivicTheme's component schema where the sub-theme is overriding components, it should attempt to extract all the variables from the twig template and import into the schema.
