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.

refactor(es/minifier): Merge cond_init with reassigned (#6850) 
**Description:**

And optimize the following situation
```js
export function genElement(el, state) {
    if ('slot' === el.tag) return el1 = el, genChildren(el1);
    if (el.component) {
        var el1
        return 999;
    }
}
```
which rarely happens in hand written JS, but is often generated by swc merge variable pass.
