Inconsistent variable naming

[0x0blu]

Describe the bug

SWC generates wrong variable names if it collides with object type definition key.

In the image you can see that it transpiles event to event1 everywhere except in the last line, which of course throws an error.

Input code

import type X from './types';

const event = {};

setTimeout(() => {
  console.log(event)

  const actions: { [event in string]?: void } = {};

  console.log(event)
}, 1000);

I guess it's the same problem as #6533, which was fixed in #6597. You might need to wait for the next version of swc.

You would see the problem solved in 1.3.22
