refactor(semantic)!: remove SymbolFlags::Export ( #7414 )
...
close : #7338
close : #7344
The `SymbolFlags::Export` is Initially used to solve `ExportSpecifier` that is not `IdentifierReference` that causes we cannot determine whether a Binding is not used everywhere by `Semantic`.
Since #3820 this problem is solved, so we don't need `SymbolFlags::Export` no longer. Also, removing this can help us easier to pass the `Semantic` check in `Transformer`

### Changes
1. The left-hand of `AssignmentExpression` is always `ReferenceFlags::Write`
```js
let a = 0;
console.log(a = 0);
^ Write only
```
2. The `argument` of `UpdateExpression` is always `ReferenceFlags::Read | Write`
```js
let a = 0;
a++;
^ Read and Write
```
This change might cause some trouble for `Minfier` to remove this code, because ‘a’ is not used elsewhere. I have taken a look at `esbuild` and `Terser`. Only the `Terser` can remove this code.

fix(transformer/async-to-generator): arguments isn't correct after transformation ( #7234 )
...
Fix due to this plugin transforming the async method and async arrow function, it caused arguments no longer point the original function.
For example:
Before
```js
class Cls {
async method() {
() => {
console.log(arguments)
}
}
}
```
After:
```js
class Cls {
method() {
var _arguments = arguments;
return babelHelpers.asyncToGenerator(function* () {
() => {
console.log(_arguments);
};
})();
}
}
```
In this way, the `_arguments` is its original function's arguments
### For performance regression
It seems we need to check the IdentifierReference and BindingIdentifier if it's an `arguments`, that causes a significant regression, we may need a cheap way to do checking

fix(transformer/async-to-generator): incorrect transform when super expression is inside async method ( #7171 )
...
After transformation, super expressions have moved to unexpected places. This PR replaces super expression to call expression, and then inserts the super methods to the top of the method body.
For example:
Before:
```js
class G {
async method() {
super.foo()
}
}
```
After:
```js
class G {
method() {
var _superprop_getFoo = () => super.foo,
_this = this;
return _asyncToGenerator(function* () {
_superprop_getFoo().call(_this);
})();
}
}```

refactor(transformer/async-to-generator): move handling of MethodDefinition's value to exit_function ( #7105 )
...
Part of #7074
We need to handle this before the `arrow_function` plugin inserts `_this = this` because, in the `async-to-generator` plugin, we will move the body to an inner generator function. However, we don't want `_this = this` moved to the inner generator function as well. So as long as we move first, and then insert, we can fix this problem.
The new semantic error is related to another tricky problem, I will fix it in another PR
