fix: better render type

[paoloricciuti]

Svelte 5 rewrite

Closes #11996

For the moment i've excluded $$slots and $$events from the Props in the second argument but we can add them back in.

Also for the moment i've allowed the user to pass a ComponentType while still inferring the props...this is the case if the user is using some old svelte 4 library with old .d.ts. Again if this is not desirable we can change that.

No test because it's just at the type level.

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.
