`design:type`/`design:paramtypes`/`design:returntype` is wrong for Enums in a different module

[翠]

Describe the bug

When using a type from a different module in a property or method that has a decorator and emitDecoratorMetadata is enabled, SWC uses typeof Namespace === "undefined" || typeof Namespace.TypeName === "undefined" ? Object : Namespace.TypeName as the value to pass to _ts_metadata.

This is wrong because Namespace.TypeName could be a enum. If it's an enum, the value should be Number or String depending on the definition of that enum. But the code emit by SWC returns Object.

TypeScript emits typeof (_b = typeof Enums !== "undefined" && Enums.Options) === "function" ? _b : Object, which does not have this problem.

Input code

import * as Enums from './enums'

function decorate() {}

class Foo {
  @decorate()
  foo(options: Enums.Options): Enums.Options {}

  @decorate()
  bar: Enums.Options
}

SWC Info output

No response

Expected behavior

The output uses typeof (_b = typeof Enums !== "undefined" && Enums.Options) === "function" ? _b : Object, which avoids this problem.

Actual behavior

The output uses typeof Enums === "undefined" || typeof Enums.Options === "undefined" ? Object : Enums.Options, which has this problem.
