keep origin js exception info in error

[hardfist]

It seems that esbuild will convert js exception info in plugin to string，which is inconvenient to do some logging according to the exception message。

import esbuild from 'esbuild';

const {build} = esbuild
class MyException {
  constructor(code, message,detail){
    this.code = code;
    this.message = message;
    this.detail = detail
  }
}
async function mybuild() {
  const result = await build({
    entryPoints: ['./src/index.js'],
    bundle: true,
    sourcemap:true,
    write:false,
    format: 'esm',
    plugins: [{
      name: 'esbuild',
      setup(build){
        build.onResolve({filter: /.*/},() => {
          throw new MyException(10086, 'encode error', {a:1,b:2})
        })
      }
    }]
  })
}
async function main(){
  try {
    await mybuild();
  }catch(err){
    console.log('myerr:', err.message, err.errors[0])
  }
}

main();

which generate the following error info

it would be helpful to adding the origin serialized exception in the error,something like

errors: [{
  location: null,
  text: '[esbuild] encode error',
  originInfo: JSON.stringify(myexception)
}]

which we could parse the originInfo to get originException, so as to do some business logic according to exception
