Multiple choice polls

[dali99]

Your use case

What would you like to do?

Answer a multiple choice poll with multiple answers

Why would you like to do it?

Often you'd be okay with multiple outcomes. For example for planning around time slots

How would you like to achieve it?

By clicking the polls items

Have you considered any alternatives?

The most often used alternative is to just type out messages and use reactions as polls instead.

Additional context

The current spec proposal for polls matrix-org/matrix-spec-proposals#3381 has multiple choice in it,
But it seems this was added after some of the implementations were made (IIRC polling existed in RiotX)

This is a pretty low priority thing since the workaround is so simple. But I was surprised when I made a multiple choice poll manually and it couldn't be properly answered. (And didn't see an issue about it) So adding this for tracking purposes.

This was already implemented for Element Web. However, the PR matrix-org/matrix-react-sdk#9519 was rejected because it wouldn't be cross platform across all versions of Element. I would be happy to implement this for iOS (both Element and Element X) and I might also take a look at Android. Could you please confirm that this would get merged (if my code meets all requirements, etc.)
