[Enhancement] Unify the home dir

[WJ66880]

Before Creating the Enhancement Request

• [x] I have confirmed that this should be classified as an enhancement rather than a bug/feature.

Summary

unify the home dir

Motivation

When I try to start rocketmq 5.2.0 by src locally, I have to config the home directory nearly for every part of rocketmq, such as namesrv, proxy, broker, brokercontroller, brokercontainer, mqadmin, acl and so on. Especially manually. The config almost share the same directory path. It's a tedious work. So I suggest to unify the rocketmq home directory.
