Compiling esm esm cannot be used directly in the bundler module

Bug description

Compiling esm code cannot be used directly in the bundler module，.e.g:

The Object.assign cant work. Because bundle module is not the same as browser esm.module export variable just only have getter.

Steps to reproduce

1. use binding @external("../test","test")
2. complie esm code

3. I hava a Compatibility method,but i think Not good enough.

AssemblyScript version

^0.27.0

I suppose the solution is to use Object.defineProperties() instead of Object.assign()

Yes, the above code is just to ensure that the current compiled results work.

Same problem.
Generated binding to esm:

const __module0 = imports["./main.js"];
const adaptedImports = {
  "./main.js": Object.assign(Object.create(__module0), {
    myFunc(x) {
      // assembly/index/my_func(i32) => bool
      return __module0.myFunc(x) ? 1 : 0;
    },
  }),
};

In Chrome and Vivaldi works fine.
if Firefox throw:

Uncaught TypeError: "myFunc" is read-only

If I edit manually to

const __module0 = imports["./main.js"];
const adaptedImports = {
  "./main.js": Object.assign({
    myFunc(x) {
      // assembly/index/my_func(i32) => bool
      return __module0.myFunc(x) ? 1 : 0;
    },
  }),
};

or to

const __module0 = imports["./main.js"];
const adaptedImports = {
  "./main.js": Object.create(__module0),
};

it works.
Also works when calling func via globalThis in env.ts:

// env
@external("env", "myFunc")
export declare function my_func(x: f32): boolean

main.ts:

// ./main.js
globalThis.myFunc = (x: number): boolean => {
  console.info('main.js myFunc()');
  return true;
}

But manual edits or calls through a global object are unnecessary work.
