refactor: plugin container

[antfu]

Redo #16740 against main.

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

Awesome! If we want to merge this one before v6, let's do it in 5.3

Only one nit but otherwise looks great! Glad to see ecosystem-ci passing too.
