[Story] EX LLS: reply and thread

[bmarty]

Description

• As a user
• I want to be blocked to perform certain actions that does not work or does not make the UX good
• So that the actions that I do work and the UI/UX stays consitent

Acceptance criteria

• When a LLS is started, user cannot reply to the state Event org.matrix.msc3672.beacon_info. This is not supported by the Rust SDK, and so it does not work. When the reply is done by Element Web, it works, and the rendering is OK on EXA. But better to disable the ability to reply to such Events globally.
• User cannot create a thread from a LLS start/stop Event
• User cannot create a LLS from a thread timeline. Currently the LLS is started but there is no immediate UI feedback as the banner is only rendered on the Main timeline on mobile. It's probably better to disable the ability to start a LLS from a thread.

It seems that the SDK provides true for EventTimelineItem.canBeRepliedTo, so there is something to do SDK side for the first and second acceptance criteria. I have created matrix-org/matrix-rust-sdk#6562 to track this.
