Fix attempted import error for react (#61791)
### What
Exclude precompiled react packages from browser layer loaders coverage.
### Why
Since we're transpiling all the browser layer code now after #59569,
then SWC will also compile react. But when it compiles
`react.production.min.js` it gives me with the code and ESM helper
inserted
```js
import { _ as _type_of } from "@swc/helpers/_/_type_of"; // This is not correct
var l = Symbol.for("react.element"), n = Symbol.for("react.portal"), p = Symbol.for("react.fragment"), q = Sym
bol.for("react.strict_mode"), r = Symbol.for("react.profiler"), t = Symbol.for("react.provider"), u = Symbol.f
```
This makes bundler think it's a ESM package but actually it's CJS, which
converts the module into `{ default: .., __esModule }` instead of the
original react module.
When you're using `React.useEffect` or other API through namespace
import (`import * as React from 'react'`), this will break the module
exports check in bundling as the property doesn't directly attached to
the module now. This PR disabled the transform for precompiled react
packages now and will see the deeper issue in next-swc side later.
