Value of `netlifyConfig.build.processing` passed to plugins does not reflect values set in the UI

[ascorbic]

Describe the bug

If a site has enabled post-processing in the UI, this fact is not exposed in the config object passed top plugins. This is in contrast to other build settings which do include UI values. It would be useful to have acess to this, because frameworks may need to warn a user if it is incompatible with their settings. See opennextjs/opennextjs-netlify#994

Configuration

• Enable post-processing on a site
• Log value of netlifyConfig.build.processing in onPreBuild
• Observe it is always set to { css: {}, html: {}, images: {}, js: {} }

Thanks for finding this bug @ascorbic.

This is a bug in Bitballoon and the buildbot. I have filed https://github.com/netlify/buildbot/issues/1911 to keep track of it. The problem and its solution seems to be quite straightforward.
