Support non-JavaScript identifier token in default export

[mizdra]

close: #323

Future Works

• There is a bug where no-unused-class-names reports a-1 as unused even though it is used in styles['a-1'].
  • no-unused-class-names rule should mark styles['foo'] and styles["foo"] as using class names #125
• Theoretically, we should be able to support non-JavaScript identifier tokens in named exports as well.
  • This could likely be achieved using "Arbitrary module namespace identifier names".
    • Normative: Arbitrary module namespace identifier names tc39/ecma262#2154
  • Since this would be a large change, it is outside the scope of this PR.

Special Thanks

@apple-yagi created a proof of concept in #309 and #320, demonstrating that this feature is feasible. He also provided key ideas for implementing this feature, specifically the concept of multiple mapping objects, alongside me (ref: #309 (comment)). Thank you!

This patch exists solely to pass tests. Typically, users won't encounter issues without it. The reason is explained at https://github.com/mizdra/css-modules-kit/pull/330/changes#diff-dfca5f15f8422ee53dd53de71429e82487d16f8582cbec09ee9943d5c8a84978R16-R20.

I plan to release without patching getReferencesAtPosition. If there are any issues, users will likely report bugs.
