fix(es/react): Make jsx with single spread child static (#8339) 
**Description:**

Example:
```js
<h1>{...a}</h1>
```
Before:
```js
_jsx("h1", {
    children: [
        ...a
    ]
})
```
After:
```js
_jsxs("h1", {
    children: [
        ...a
    ]
})
```

Following the implementation in [Typescript](d4fbc9b57d/src/compiler/transformers/jsx.ts (L340)), jsx with a single spread child should also be considered as static jsx.

feat(es/minifier): Respect inline level and preserve native names (#8205) 
**Description:**

Note: Preserving native names is a hack, but it's used by `terser` and it's the only way to preserve the name of `class AbortSignal` while mangling without `keep_classnames: true`. We can special case `AbortSignal`, but let's just follow `terser`.

feat(es/testing): Use __swc_snapshots__ for test! macro (#8191) 
**Description:**

This implements something similar to `__snapshots__` of `jest`. Instead of storing the expected result as a string literal, we now store it in `$crate/tests/__swc_snapshots__/$path_to_test__$test_name.js`.

 - Closes #4509

refactor(atoms): Remove usage of js_word! to drop string-cache (#7976) 
**Description:**

This PR is to prepare removal of `string-cache`. Actually, this PR does not remove it. Instead, this PR only removes direct usages of `js_word!`s, especially in patterns.
