fix(es/helpers): Fix metadata of decorators being undefined

[sschen86]

when use "decorator stage3" with this option that context.metadata will be undefined

const option = {
    jsc: {
        parser: {
            syntax: 'typescript',
            decorators: true,
        },
        transform: {
            decoratorVersion: '2022-03',
        },
        target: 'es5',
        externalHelpers: true, // external @swc/helpers
    },
    module: {
        type: 'es6',
    }
}

if set externalHelpers to false, context.metadata is right

example code

function Get() {
  return (value, context) => {
    console.info(context.metadata); // out undefind
  };
}

class MyClass{
    @Get()
    doSome(){
        //..
    }
}

Why did you revert changes in swc_ecma_transforms_base?

Why did you revert changes in swc_ecma_transforms_base?

What, pray, is the meaning of this?

I only modified this file（packages/helpers/esm/_apply_decs_2203_r.js） and added the missing variable metadata

I misread it. Sorry.

This file is correct and there is no missing variable metadata. It does not need to be modified
