feat: migrate Component to ReturnType<typeof Component> in TS

[paoloricciuti]

Svelte 5 rewrite

Closes #13491

I added the migration only for TS because with JSDoc would be immensely more complex (unless i'm missing something) because we would basically need to parse the JSDoc comment ourselves.

WDYT?

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.

What are your thoughts on #13441. Merging that and instead of ReturnType<typeof Component> use ComponentExports<typeof Component>.

I think it could be interesting...is the language server returning the same type also for legacy components? If i remember they use a different type right @dummdidumm ? Would this type work in that case?

[FoHoOV]

@paoloricciuti AFAIK everything is of type Component, it has the legacy types in it for now.
