[Visual Refresh] Provide legacy JSON theme tokens

[mgadewoll]

Summary

closes https://github.com/elastic/eui-private/issues/138

Important

This PR merges into a feature branch.

This PR adds legacy JSON token files for the new theme.
These files were copied from the current theme and values updated according to the new theme specifications. Additionally tokens for accentSecondary have been added.

Note

No other additional tokens were added as these files are only meant to support existing usages and not promote new usages.

QA

• CI passes
• added testing packages on Kibana test instance update expected UI (e.g. editors and dashboard panels)
• EUI docs:
  • sass token docs work as before for current theme and updates values when switching to new theme

The changes look great, but the Sass token docs seem to be broken now. Could you please take a look?

@tkajtoch Could you specific why was broken in your testing? Cause for me it looks to be working as expected 🤔

[mgadewoll]

@tkajtoch Thanks for pointing out the issue with docs not loading.
I fixed it in this commit. The issue was that a theme might not have been set yet to check on.
