Motion: export duration variables in JavaScript with the carbon/motion package

[jendowns]

Summary

Currently the @carbon/motion package exports carbon--motion JavaScript function with easings. But as far as I know, there isn't a way to also import any specific timing values (like the equivalent of SCSS variable $duration--fast-02) as JavaScript variables from this package.

Justification

When creating JavaScript-based animations, it is helpful to be able to import these variables from Carbon instead of doing workarounds and/or redefining the variables ourselves.

If these values actually do exist in a package right now, please let me know! I just didn't see a way to grab these motion duration values currently. Thank you!
