feat(stream): add XACKDEL command

[i18nsite]

fix : https://github.com/apache/kvrocks/issues/3120 （只写了XACKDEL）

This commit introduces the XACKDEL command for Redis streams with support for different acknowledgment strategies:

• KEEEREF: acknowledge entries in the specified group
• DELREF: acknowledge entries and remove from all other groups' PELs
• ACKED: acknowledge entries only if they are acknowledged by all groups

The command follows the syntax: XACKDEL key groupname strategy IDS numids id [id ...]

It returns an array of integers indicating the acknowledgment status for each entry ID.

我不懂c++

代码都是gemini3写的，因为xack和xdel都有实现，所以问题不大

让ai对照文档写了比较详细的测试，用下面的脚本可以测试

❯ cat test_xackdel.sh
#!/usr/bin/env bash

set -e
DIR=$(realpath $0) && DIR=${DIR%/*}
cd $DIR
set -x

./x.py format
./x.py build

cd tests/gocase
go test -v ./unit/type/stream/ -run TestXAckDel -args -binPath=$(pwd)/../../build/kvrocks -workspace=$(pwd)/workspace
go test -v ./unit/type/stream/ -run TestXAckDelDocExample -args -binPath=$(pwd)/../../build/kvrocks -workspace=$(pwd)/workspace
