refactor: plugin container for Vite 6

[antfu]

This PR refactors the plugin containers file:

• PluginContext per-plugin, instead of per-hook, align with rollup: https://github.com/rollup/rollup/blob/1b62c336b8e927e846cd2c04563ae0868a5d5832/src/utils/PluginDriver.ts#L105-L110
• Hoisted Context and TransformContext classes to top-level instead of having them in the function that creates every time.
• Make EnvironmentPluginContainer a class to have more explicit deps relationships and easier to work with

I've yet to thoroughly review this, but wondering, could this be refactored in main? Seems like a nice general refactor otherwise so we keep the environment API changes small. Or does it introduces breaking changes?

[antfu]

It's based on the new abstraction of the new env pluginConainter - it would require certain efforts to redo it in main - and then solving the conflicts in v6 as well. Do you think that would be worth the effort?

[antfu]

Ok, I will try to redo this on main, so we could also at least ensure it works without env api
