When webpack plugins try to access hooks that don't exist in rspack, provide a clear error message instead of the cryptic "Cannot read properties of undefined (reading 'tap')". The error message explains: - Which hook is not supported - That this typically happens with webpack plugins - Lists all available hooks for reference This helps developers quickly identify webpack compatibility issues.

Summary
When Webpack plugins try to access hooks that don't exist in rspack, provide a clear error message instead of a cryptic message, e.g. "Cannot read properties of undefined (reading 'tap')" (attempting to use
pino-webpack-pluginwith rspack).The error message explains:
This helps developers quickly identify webpack compatibility issues.
While I haven't tested it, this should hopefully catch #12617 as well way before the panic.
