Create spaces (#5982)

* Allow creating a space with `CreateRoomParameters`

* Add 'Create space' menu item in the spaces home screen. Also, imports new strings related to spaces.

* Link the 'Create space' button with the screen to create the space

* Unify room access and visibility for `ConfigureRoom`, use the updated design

* Fix `EditRoomDetails` avatar size (68dp)

* Replace `EditableAvatarView` and `UnsavedAvatar` copmonents with `AvatarPickerView`

* `AvatarDataFetcherFactory`: Make sure we use a fallback image fetcher when the URL is not an MXC one (a local one, i.e.). This removes the previous need for a separate `UnsavedAvatarView`

* Use `AvatarPickerView` in all the screens where `EditableAvatarView` was used

* Improve naming and previews

* Update strings, remove unused ones for `RoomAccessItem`

* Make `isSpace` part of the `CreateRoomConfig`

* Ensure the content fits in the screenshots for `AvatarPickerSizesPreview`

* Add `AvatarDataFetcherFactoryTest`

* Add new feature flag for creating spaces

* Fix ripple being too large for the `Pick` state

* Tweak margins and section titles a bit

* Add preview for `HomeTopBar` with the spaces case

* Update screenshots
