fix: allow for more svelte-ignore to work

[paoloricciuti]

Svelte 5 rewrite

Closes #11822

I had this idea of using a WeakMap to keep the ignore list for every node...it works well except for store_rune_conflict because that's invoked even before the ast is walked. But i also think it make no sense to silence that warning.

I don't know if this is good solution or not but i just leave it out there, if it's not desired obviously feel free to close. 😄

Please note that the Svelte codebase is currently being rewritten for Svelte 5. Changes should target Svelte 5, which lives on the default branch (main).

If your PR concerns Svelte 4 (including updates to svelte.dev.docs), please ensure the base branch is svelte-4 and not main.
