how to makeresbuld to support multi compiler of webpack

Rsbuild will internally create multiCompiler when the output.targets contains more than one value.

For example, if output.targets is ['web', 'node'], Rsbuild will create one compiler for the web target and another compiler for the node target.

And currently this is the only way to create a multiCompiler in Rsbuild.

For example, I think this is useful for the same target web Turn on multiple compiler debugging modes while launching custom entries

We have plans to add similar webpack multi compiler APi Allow us to manually start multiple independent processes at the same time?

You can use Rsbuild's JavaScript API to create multiple rsbuild instances and call their build methods at the same time.
