Support JS output of only breakpoints

[blackfalcon]

Is your feature request related to a problem? Please describe.

If a user wants to use breakpoints from design tokens in javascript, the only way is to consume ALL the tokens.

Describe the solution you'd like

Create an export of a simpler object that a user could consume and easily parse to use breakpoints in JS solutions.

Describe alternatives you've considered

Not doing it and just sticking with ALL TOKENS as a useable solution.

Additional context

Exit criteria

This issue can be closed once there is a demonstratable export of breakpoint design tokens in a JS object for consumption.

Additionally, all documentation needs to be updated to support this new featured export of data.
