Add test coverage for styled-jsx jsx prop on <style> elements via module augmentation

[Copilot]

Users reported <style jsx> (styled-jsx pattern, common in Next.js) producing TS2322: Property 'jsx' does not exist on type 'DetailedHTMLProps<StyleHTMLAttributes<HTMLStyleElement>, HTMLStyleElement>' in typescript-go while the standard TypeScript extension showed no error.

Investigation findings:

• Both TypeScript and typescript-go behave identically: the error appears only when styled-jsx types are absent, and disappears when they are present
• The user's discrepancy is a project configuration difference — Next.js auto-includes styled-jsx types via next-env.d.ts → /// <reference types="next" /> → styled-jsx/global.d.ts, and the typescript-go extension may resolve the project in a different context
• The module augmentation pattern (declare module 'react' { interface StyleHTMLAttributes<T> { jsx?: boolean } }) works correctly in typescript-go across all loading mechanisms: import, /// <reference types>, types[] in tsconfig, and transitive chains

Changes:

• Adds testdata/tests/cases/compiler/jsxStylePropStyledJsx.tsx — a regression test using react16.d.ts + declare module 'react' augmentation (the exact styled-jsx pattern) verifying that <style jsx>, <style global>, and <style jsx global> compile without error, while truly unknown attributes still correctly fail
• Adds baseline files (symbols, types) for the new test

declare module 'react' {
    interface StyleHTMLAttributes<T> extends HTMLAttributes<T> {
        jsx?: boolean;
        global?: boolean;
    }
}

const a = <style jsx>{`h1 { color: red; }`}</style>;      // no error
const b = <style global>{`h1 { color: red; }`}</style>;   // no error
// @ts-expect-error
const d = <style unknown>{`h1 { color: red; }`}</style>;  // correctly errors
