The fixing is done by removing everything between the identifier and the opening parenthesis (without taking comments into consideration)

Pull request:
Fix: space-before-function-paren autofix removes comments (fixes #12259)
<!--

-->

**What is the purpose of this pull request? (put an "X" next to item)**

[X] Bug fix #12259

This PR fixes the `space-before-function-paren` rule fixer with the `"never"` option, to:

* Concatenate block comments instead of removing them.
* Report error but doesn't fix anything if there is a line comment between.

Example:

function foo /* */(){}

function bar /* 1 */

function baz // line comment

Current autofix behavior:

```js
/* eslint space-before-function-paren:["error", "never"]*/

function foo(){}

function bar(){}

function baz(){}
```

New autofix behavior:

```js
/* eslint space-before-function-paren:["error", "never"]*/

function foo/* */(){}

function bar/* 1 *//* 2 *//* 3 */(){}

function baz // line comment
(){}
```

`baz` is reported, but not auto-fixed.
