[feature](compaction) Add an http action for visibility of compaction score on each tablet (#38489)

[Hastyshell]

pick: #38489

Usage:

1. curl http://be_ip:be_host/api/compaction_score?top_n=10 Returns a json object contains compaction score for top n, n=top_n.

[
{
"compaction_score": "5",
"tablet_id": "42595"
},
{
"compaction_score": "5",
"tablet_id": "42587"
},
{
"compaction_score": "5",
"tablet_id": "42593"
},
{
"compaction_score": "5",
"tablet_id": "42597"
},
{
"compaction_score": "5",
"tablet_id": "42589"
},
{
"compaction_score": "5",
"tablet_id": "42599"
},
{
"compaction_score": "5",
"tablet_id": "42601"
},
{
"compaction_score": "5",
"tablet_id": "42591"
},
{
"compaction_score": "5",
"tablet_id": "42585"
},
{
"compaction_score": "4",
"tablet_id": "10034"
}
]

If top_n is not specified, return all compaction score for all tablets. If top_n is illegal, raise an error.

invalid argument: top_n=wrong

2. curl http://be_ip:be_host/api/compaction_score?sync_meta=truesync_meta is only available on cloud mode, will sync meta from meta service. It can cooperate with top_n.
   If add param sync_meta on non-cloud mode, will raise an error.

sync meta is only available for cloud mode

3. In the future, this endpoint may extend other utility, like fetching tablet compaction score by table id, etc.
