[Enhancement] Append LIST partition info when list table partitions by rest api.

[plotor]

Why I'm doing:

You can learn about the background from PR #52682.

What I'm doing:

This PR is a supplement to #41938, and append LIST partition info when list table's partitions by RESTful API. For example, for the following LIST partition table:

CREATE TABLE `tb_list_partition` (
  `c0` bigint(20) NOT NULL COMMENT "cc0",
  `c1` datetime NOT NULL COMMENT "cc1",
  `c2` varchar(32) NOT NULL COMMENT "cc2",
  `c3` decimal(32, 8) NULL DEFAULT "0" COMMENT "cc3",
  `c4` array<int(11)> NULL COMMENT "cc4",
  `c5` struct<C4_a int(11), c4_b struct<c4_b_1 varchar(65533)>> NULL COMMENT "cc5",
  `c6` map<bigint(20),map<int(11),varchar(65533)>> NOT NULL COMMENT "cc6",
  `c7` json NOT NULL COMMENT "cc7",
  `c8` bitmap NOT NULL COMMENT "cc8",
  `c9` hll NOT NULL COMMENT "cc9",
  INDEX idx_bitmap (`c9`) USING BITMAP COMMENT ''
) ENGINE=OLAP
PRIMARY KEY(`c0`, `c1`, `c2`)
PARTITION BY LIST(`c2`)(
  PARTITION p1 VALUES IN ('beijing'),
  PARTITION p2 VALUES IN ('shanghai', 'hangzhou'),
  PARTITION p3 VALUES IN ('guangzhou', 'shenzhen'),
  PARTITION p4 VALUES IN ('chengdu', 'chongqing')
)
DISTRIBUTED BY HASH(`c0`) BUCKETS 8
PROPERTIES (
"enable_persistent_index" = "true",
"replication_num" = "3"
);

The /api/v2/catalogs/{catalog}/databases/{db}/tables/{table}/partition API will return the LIST partition information through the inKeys field:
