[feature] Add /ban and /banip as built-in commands

[wu-vincent]

Is your feature request related to a problem? Please describe.
Currently, the /ban and /banip commands are missing from the default command set in BDS.

Describe the solution you'd like

1. Implement the /ban and /banip commands to ban online players.
2. Add the ability to ban offline players who have previously joined the server.

Additional context
BDS stores player data using their UUID as the key in leveldb with the prefix player_. To be able to ban offline players by name, we need to maintain a mapping between player names and their UUIDs. This mapping should be stored in a separate file, which should be updated each time a player joins the server. In Bukkit, a similar file called usercache.json exists so we could potentially use a similar format.

Once we have access to player data from leveldb using the username, we will also need to store additional data (e.g., last seen IP address). This could be stored in an additional compound tag, possibly named endstone.
