svelte2tsx each block typing

[jasonlyu123]

Describe the bug
svelte2tsx use Array.map to mimic each block now but the svelte compiler use for-loop to iterate.

quote doc:

You can use each blocks to iterate over any array or array-like value — that is, any object with a length property.

To Reproduce
Steps to reproduce the behavior:

https://svelte.dev/repl/c7b9f67bfbe24c5dbc06407140618b84?version=3.24.0

Expected behavior
create another map/forEach function that accepts arrayLike interface to wrap it

Screenshots
If applicable, add screenshots to help explain your problem.

nitpick here. await block also should be changed to use PromiseLike interface
