This adds a specialization of the styled-components api, which is correctly typed according to the new theme variable type definitions included in EUI (elastic/eui#1750) and made available in Kibana via #33873.

Summary
This enhances the
compile-scss.jsbuild script to also emit TypeScript type definitions for the JSON files generated from the theme variables. These type definitions are stored as.json.d.tsfiles indist/alongside the JSON files so the imports are typed correctly.When imported in downstream projects like Kibana, the imported symbols will be typed appropriately, which would reduce the risk involved in making breaking changes to these variables like #1590 did.
Letting the TypeScript compiler derive the types automatically was attempted twice in Kibana (elastic/kibana#24425 and elastic/kibana#25516). Both attempts failed due to limitations Kibana's build process and the TypeScript compiler.
