Incompatibility with css-loader due to its use of createHash

[issacgerges]

• Operating System: MacOS
• Node Version: 20
• NPM Version: 10.5.0
• webpack Version: 5.90.3
• thread-loader Version: 4.0.2

Expected Behavior

thread-loader is compatible with css-loader

Actual Behavior

The following exception is raised at runtime

Cannot read properties of undefined (reading 'util')
    at PoolWorker.fromErrorObj (/some_dir/node_modules/thread-loader/dist/WorkerPool.js:302:12)
    at /some_dir/node_modules/thread-loader/dist/WorkerPool.js:184:29
    at /some_dir/foo/bar/file.less:1:1
    at defaultGetLocalIdent (/some_dir/node_modules/css-loader/dist/utils.js:323:37)

Code

css-loader expects to be able to create hashes via an exposed loader/webpack api. thread-loader doesn't expose these over the processes bridge so hitting this code will always errror.

How Do We Reproduce?

Specifying any of the localIdent configuration options on css-loader and running it in thread-loader should be enough to repro.

Additional questions

I reported this as a bug since it seemed previously compatibility with css-loader was intended. If that's still the case, is there a better way for them to create hashes?

We need to pass util api to to loader context, feel free to send a PR
