feat: better way to avoid optimize twice

[SyMind]

This PR contains a:

• bugfix
• new feature
• code refactor
• test update
• typo fix
• metadata update

Motivation / Use-Case

Overwriting buildMeta is not supported in Rspack.

And, I think it would be better to use a WeakMap to map imageMinimizerPluginInfo for a module. Because the imageMinimizerPluginInfo only used in this plugin.
