refactor: refactor JsxRuntime namespace to JsxRuntimeOptions

The commit refactors the JSX runtime handling code by:

1. Renaming JsxRuntime namespace to JsxRuntimeOptions
2. Splitting logic into getFromContext() and getFromAnnotation() methods
3. Moving regex constants to shared RegExp.ts
4. Simplifying options handling and annotation parsing
