Add "start video call" button in compose

[gnprice]

This Zulip feature: https://zulip.com/help/start-a-call

Zulip makes it convenient to add a video or voice call link to any message, using the call provider (Jitsi, Zoom, etc.) configured by your organization's administrators.

This is a feature the legacy app had, and would be good to add here. We've had one user request for it: #mobile > Missing "Start Jitsi Meeting" button in mobile app @ 💬
