WIP | feat: update css to latest

[castastrophe]

Description

This is a full upgrade of all packages to use the latest published CSS from the @spectrum-css project.

Why update everything at once?

It is often easier to see changes in components that influence one-another (i.e., --mod passthrough styles from parent components) if we bump all components together.

That does not mean that all components need to be merged via this PR but rather, that all components can be viewed in unison via this PR.

Related issue(s)

Most related issues exist in Jira but this is a nice view of the scope of updates we are still needing in order to be up-to-date with the latest fast-follows design updates and CSS theming optimizations (these optimizations have removed hundreds of extemporaneous custom properties.

How has this been tested?

• Strongly recommend relying heavily on the VRT results and sanity-checking the Storybook pages by clicking through some of the more problematic components (especially those with nested SWC components or styles from multiple CSS packages).

• Strongly suggest design review this Storybook for their most important components and validate the S2 versions are as they wish. This PR is up-to-date with the latest fast-follows that have been merged.

• Did it pass in Desktop?

• Did it pass in Mobile?

• Did it pass in iPad?

Screenshots (if appropriate)

Types of changes

• Bug fix (the semver designation as this update bumps the preview theme for S2 which is not the foundational theme in this release as-yet).
• Breaking S2 design change (this does not translate to the semver used but is an important distinction)

Review the following VRT differences

When a visual regression test fails (or has previously failed while working on this branch), its results can be found in the following URLs:

• Spectrum | Light | Medium | LTR
• Spectrum | Dark | Large | RTL
• Express | Light | Medium | LTR
• Express | Dark | Large | RTL
• Spectrum-two | Light | Medium | LTR

If the changes are expected, update the current_golden_images_cache hash in the circleci config to accept the new images. Instructions are included in that file.
If the changes are unexpected, you can investigate the cause of the differences and update the code accordingly.
