`eval?.()` is now an indirect eval

Bug Report

There has apparently been a recent change to the behavior of eval?.() in all major JavaScript engines. It is now considered an indirect eval instead of a direct eval. This behavior was changed in July 2020. TypeScript is still compiling it as a direct eval and I didn't see an issue about this, so I created this issue.

💻 Code

globalThis.a = "global";
(a => eval?.("console.log(a)"))("local");

🙁 Actual behavior

When compiled with TypeScript, this prints local instead. That matches the behavior of older JavaScript runtimes such as node v14 but doesn't match the latest JavaScript runtimes.

🙂 Expected behavior

This code now prints global when run in an up-to-date browser or in node v15, so it should print global when compiled with TypeScript as well.

Comienza compilando y ejecutando el ejemplo de Playground proporcionado en un runtime de JavaScript actual y, después, compara el JavaScript emitido con el resultado global frente a local informado. El payload no menciona archivos fuente ni tests, así que localiza la ruta del compilador que gestiona las expresiones de llamada opcional y añade cobertura que muestre el comportamiento esperado de indirect-eval.
