Implement 'create from React component' logic

[astone123]

Implement all of the server-side logic that we need for Create from React Component feature. This should include

• React component spec file template (see packages/data-context/src/codegen/templates/vue-component/vue-component.ejs for example)
• Query that takes a path to a file and returns a list of React components in that file, using react-docgen to parse the file

See the Create from React Component tech brief for guidance

The code for this is done in cypress-io/cypress#24881, but has yet to be released.
We'll update this issue and reference the changelog when it's released.
