feat(components): remove ember-get-config

[aklkv]

📌 Summary

ember-get-config is problematic in vite world and doesn't work without a hack this hack will not be release and it is advised to move to @mbroider/macros

This just does that for components and website (which was pretty strange usecase)

• bonus I removed no longer needed ember-unique-id-helper-polyfill support for this feature in included ember-source > v4.4 - let me know if you want me to split it out
