fix: use indirect eval to prevent local scope access in repl playground

[FoHoOV]

Fixes #11329. Currently repl is using direct eval to run the compiled output which results in accessing the local variables where the eval is called with the compiled output of REPL code. Another issue is that it can also access global scoped variables within its iframe such as counter, original_timeend and etc. This change will fix these issues.

Svelte 5 rewrite

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.
