Make XMTP specific macro for cleaning up logs

[insipx]

we have lots of logs like this, esp in mls sync code:

                tracing::info!(
                    inbox_id = self.client.inbox_id(),
                    sender_inbox_id = sender_inbox_id,
                    installation_id = %self.client.installation_id(),sender_installation_id = hex::encode(&sender_installation_id),
                    group_id = hex::encode(&self.group_id),
                    current_epoch = mls_group.epoch().as_u64(),
                    msg_epoch,
                    msg_group_id,
                    msg_id,
                    "[{}] staged commit is valid, will attempt to merge",
                    self.context().inbox_id()
                );

they're useful when debugging, but add visual clutter to the code. we can instead create a super macro to reduce this to oneline
