Declarations that shadow global `Symbol` break emit for `using` declarations

```ts
// @lib: esnext
// @target: es2024, esnext
export class Symbol {
}

{
using _ = {
[globalThis.Symbol.dispose]() {
console.log("Hello world!");
}
};
}
```

**Expected**: Running the emitted code for both es2024 and esnext display "Hello world!".
**Actual**:

```
> node testfile.js
file:///D:/ts-track-any/testfile.js:10
if (!Symbol.dispose) throw new TypeError("Symbol.dispose is not defined.");
^

TypeError: Symbol.dispose is not defined.
```

Emitted JS code

```js
var __addDisposableResource = (this && this.__addDisposableResource) || function (env, value, async) {
if (value !== null && value !== void 0) {
if (typeof value !== "object" && typeof value !== "function") throw new TypeError("Object expected.");
var dispose, inner;
if (async) {
if (!Symbol.asyncDispose) throw new TypeError("Symbol.asyncDispose is not defined.");
dispose = value[Symbol.asyncDispose];
}
if (dispose === void 0) {
if (!Symbol.dispose) throw new TypeError("Symbol.dispose is not defined.");
dispose = value[Symbol.dispose];
if (async) inner = dispose;
}
if (typeof dispose !== "function") throw new TypeError("Object not disposable.");
if (inner) dispose = function() { try { inner.call(this); } catch (e) { return Promise.reject(e); } };
env.stack.push({ value: value, dispose: dispose, async: async });
}
else if (async) {
env.stack.push({ async: true });
}
return value;
};
var __disposeResources = (this && this.__disposeResources) || (function (SuppressedError) {
return function (env) {
function fail(e) {
env.error = env.hasError ? new SuppressedError(e, env.error, "An error was suppressed during disposal.") : e;
env.hasError = true;
}
var r, s = 0;
function next() {
while (r = env.stack.pop()) {
try {
if (!r.async && s === 1) return s = 0, env.stack.push(r), Promise.resolve().then(next);
if (r.dispose) {
var result = r.dispose.call(r.value);
if (r.async) return s |= 2, Promise.resolve(result).then(next, function(e) { fail(e); return next(); });
}
else s |= 1;
}
catch (e) {
fail(e);
}
}
if (s === 1) return env.hasError ? Promise.reject(env.error) : Promise.resolve();
if (env.hasError) throw env.error;
}
return next();
};
})(typeof SuppressedError === "function" ? SuppressedError : function (error, suppressed, message) {
var e = new Error(message);
return e.name = "SuppressedError", e.error = error, e.suppressed = suppressed, e;
});
export class Symbol {
}
{
const env_1 = { stack: [], error: void 0, hasError: false };
try {
const _ = __addDisposableResource(env_1, {
[globalThis.Symbol.dispose]() {
console.log("Hello world!");
}
}, false);
}
catch (e_1) {
env_1.error = e_1;
env_1.hasError = true;
}
finally {
__disposeResources(env_1);
}
}
```

提供された TypeScript の再現コードから始め、es2024 ターゲットと esnext ターゲットで出力される JavaScript を比較します。生成された __addDisposableResource ヘルパーと、周囲の using 宣言の出力を調べます。両方の出力が実行され、Symbol.dispose エラーなしで "Hello world!" と表示されれば完了です。
