Formation Deprecation - Step 1 - Extract CSS Library from Component Library Packages

[micahchiang]

Description

The css library is a distinct product from the rest of the component library packages and where it lives should reflect that. It currently resides in component-library/packages/ and should be moved out of that, possibly into something like component-library/libraries.

Considerations

• We may want to consider doing #1218 and #2242 first so we have a semantically accurate monorepo. If we complete 1218 first then....maybe we don't actually need to do this? Renaming our repo from component-library to something like "va-design-system" would give us a semantically accurate project structure. i.e. va-design-system/packages/css-library
• This ticket should probably be done before #1954 which is for publishing multiple packages

Acceptance Criteria

• CSS Library is moved out of component-library/packages
