consolidate all internal rollup plugin usages to Rollup config

Type of Change

Enhancement

Summary

Currently some Greenwood plugins provide their own Rollup plugins, but I think it would make more sense if those were all just declared "top level" in rollup.config.js since we're already doing that for other Rollup plugins like CommonJS and NodeJS resolution. I often forget that Greenwood has these Rollup plugins tucked away

Details

I think both of these just can get moved / imported into [getRollupConfigForBrowserScripts]
