feat: transparent shares

[JammingBen]

Description

Adds transparent sharing so share receivers can see other sharees when they have the permissions to do so.

Quite a bit of refactoring was needed for this because we didn't really support root spaces having shares. Personal spaces don't have any. Project spaces do, however, we handled them completely separate in the spaces store (via the spaceMembers prop).

Now that share root spaces can have shares, I added functionality so those shares are being handled like regular indirect folder shares within the space. I also refactored space member shares to align with that. This might be a bit confusing at first sight, but IMO it's a lot cleaner now because it's the same for all kinds of spaces.

To test the transparent sharing part you need owncloud/ocis#9943.

Hope I didn't miss anything... quite cumbersome to review. 😅 Good stuff, thank you! Also gave it a spin in the dev environment, worked like a charm. I found it quite confusing that the share roles Can view and Can edit with and without permission to list permissions have the same title. But that's not part of this repo anymore...
