chore: remove spectrum-config.js files from various packages

[blunteshwar]

Description

This PR removes all spectrum-config.js files and @spectrum-css dependencies from component package.json files as we are now maintaining styles directly within SWC.

Changes

Removed all spectrum-config.js files across component packages
Removed @spectrum-css dependencies from all component package.json files
Ensured no references to @spectrum-css remain in the codebase (outside of documentation which will be addressed in SWC-811)

Testing

Verified all instances are removed by running the following search queries:
Searched for spectrum-config (excluding .git, node_modules, .wireit, .html, CHANGELOG.md, changelog-content.md, yarn.lock, .changeset)
Searched for @spectrum-css (excluding .git, node_modules, .wireit, .html, CHANGELOG.md, changelog-content.md, yarn.lock, .changeset)

I left a question about the ui-icons package (which is an svg resource and not CSS). Otherwise, this looks good!
