Provide member object for authors of messages in context commands

[MinnDevelopment]

The interaction events for message commands provide a message object in data.resolved. This message object only includes the author but not the member in the context of guilds.

It would be nice if the message member could also be provided in these interactions, this is useful for checking roles and permissions of the message author.

Why not retrieve the member from the Discord API? I mean, it would add extra network data for bots that don't need it, not to mention Discord's point of view on the infrastructure side.

Not only is this extra work, but it also provides a degraded user experience due to slower replies. If the member is already in the interaction, the permission checks can be done immediately.
