Allow creation of unencrypted rooms

### Your use case

#### What would you like to do?
As far as I can see any room created in Element-X on Android is forced to encrypted

#### Why would you like to do it?
I Have rooms within spaces used only by me ie the rooms are restricted but I do not want messages encrypted so that if I login with an unverified device I can quickly see my data

#### How would you like to achieve it?
Mirror the web functionality which allows the user to specify if a room should be encrypted or not

### Have you considered any alternatives?

_No response_

### Additional context

I understand the point of requiring encryption for p2p messaging but not when a room is viewed as a room, not a chat. If nothing else - Element clients should behave consistently.

### Are you willing to provide a PR?

No

Start by locating the Element-X Android room-creation entry point and compare it with the web functionality referenced in the issue. Trace where room encryption is forced and identify the existing room settings flow. Done means a user can choose whether a newly created room is encrypted, with the Android behavior matching the web option.
