fix(es/minifier): Mark all function params as potential property mutation (#7409)
**Description:**

This issue is more severe than I originally thought. It raises not in
array indexing, but in function calls and property mutation. We should
treat all function arguments as potentially be property mutated,
otherwise following example

```js
class A {
	a = 1

	toString() {
		return this.a
	}
}

const a = new A()

function foo(x) {
	x.a++
}

const b = a + 1

foo(a)

console.log(b)
```

would be error(It should log 2, but logs 3 after compress).

As the result, massive regressions is unavoidable, since some of these
optimizations may indeed cause error. Part of them can be mitigated with
following optimization -- allow inline of ident even if its original
value is mutated. Consider

```js
export function foo(x) {
   const y = x
   x.a = 1
   y.b = 2
}
```

If x is a primitive value, all mutations to its properties are ignored;
if x is a object, then y refers to the same object no matter what
mutation is performed.

And there's still room for more, currently following code
```js
export function foo(x) {
    const y = Math.floor(x);
    g(y);
}
```
But I'd rather do it in a separate PR.

fix(es/renamer): Ensure that param and function body are in same scope (#7271)
**Description:**

The problem arises in L235 of swc_ecma_transforms_base/src/rename/mod.rs

```rs
unit!(visit_mut_fn_decl, FnDecl, true);
```

which calls `get_map` and evals to

```rs
node.visit_children_with(&mut v);
```

with `FnDecl` and `Analyzer` in L132. However, in `Analyzer`, a visit to raw function was not overloaded, so function arguments and function body are considered different scopes.

**Related issue:**

 - Closes #7261.
