Support rspack

[singh-jay]

If the feature solves a problem you have, specify it here.

I'm trying to migrate our webpack project to rspack, everything is working except the svg-sprites, as this project is in active development, I hope you will consider support for rspack as well.

Describe the proposed feature.

Getting error -
/node_modules/svg-chunk-webpack-plugin/lib/loader.js:20
this._module.factoryMeta = this._module.factoryMeta || {};
^

TypeError: Cannot read properties of undefined (reading 'factoryMeta')

Describe alternatives you've considered

Hello @singh-jay, thanks for your feedback.

I'm not opposed to compatibility with rspack, but it seems complicated to me because there are differences in the API.

On investigating, I can already see 2 points that pose a problem:

1. From the loader, this._module is not available with rspack and this is used to mark SVGs for the plugin (see Nested dependencies are different between development mode and production mode webpack/webpack#12202 (comment))
2. From the plugin, entry.chunks doesn't return anything. The getSvgsDependenciesByEntrypoint function allows you to search for SVG dependencies associated with an entrypoint.

@alexander-akait (Hi) What do you think?

We can add check if (this._module) {}, it prevent from crash, but I am not sure it will work correctly, need to test, also maybe we need to more API... will be great to dicussion about it with rspack team
