feat(Communities): allow for creating community permissions

This commit is the first of implementing community permissions.
**It is not implementing the complete feature**, rather does it
introduce the first pieces, such that we can get code reviewed and
merged before it grows too big.

To review these features, please make sure to

1. Enable wallet (Settings -> Advanced -> Wallet toggle)
2. Enable community permissions (Settings -> Advanced -> Community
   Permissions toggle)

You'll have to restart the app after doing so.

The commit introduces the following:

**UI, API calls and view models to CRUD community permissions**

After creating a community, the user can go to the community
settings and create new token permissions. The user can also update
and delete existing permissions.

**Asset and collectible view models**

To create community token permissions, users have to select
the token criteria. This commit introduces the `assetsModel` for ERC20
tokens and `collectiblesModel` for `ERC721` tokens.

The latter only supports custom minted community tokens at this point.

**This commit requires:** https://github.com/status-im/status-go/pull/3207
