Webpack 5's "getOptions" is missing

[ef4]

Expected Behavior

Loaders that use webpack 5's this.getOptions() API should work with thread-loader.

See webpack/webpack#10017

Actual Behavior

this.getOptions is undefined.

How Do We Reproduce?

Pick any loader that uses getOptions from loader-utils and modify it to use this.getOptions instead. That works when using webpack 5 without thread-loader, but fails when used behind thread-loader.

Anybody know how to go about fixing this?

@qnighy Can you help with this, because we need fix compatibility with webpack v5 before release

[qnighy]

@alexander-akait sure, I'll try to reproduce and fix it this weekend.

[qnighy]

It also reproduces with sass-loader@11 so I'm going to update the devDependency in thread-loader and fix the test failure.

Created a fix #113 though it's not an optimal solution.
