## Proposed changes
Issue Number: close #xxx
<!--Describe your changes.-->
1. 对hive中所有类型，除了binary(doris本身就没有binary)外都支持。
```sql
CREATE TABLE ywtest.test (
a ARRAY<TINYINT>,
b ARRAY<SMALLINT>,
c ARRAY<INT>,
d ARRAY<BIGINT>,
e ARRAY<BOOLEAN>,
f ARRAY<FLOAT>,
g ARRAY<DOUBLE>,
h ARRAY<STRING>,
i ARRAY<TIMESTAMP>,
j ARRAY<DATE>
)
stored as textfile;
INSERT INTO ywtest.test VALUES
(
ARRAY(tinyint(1), tinyint(2), tinyint(3)),
ARRAY(smallint(10), smallint(20), smallint(30), smallint(40)),
ARRAY(100, 200, 300),
ARRAY(bigint(100000000000000), bigint(20000000000000),
bigint(30000000000000), bigint(40000000000000)),
ARRAY(true, false, true),
ARRAY(float(1.23), float(4.56), float(7.89)),
ARRAY(double(10.1), double(20.2), double(30.3)),
ARRAY("apple", "banana", "orange"),
ARRAY(TIMESTAMP("2023-07-04 12:00:00"), TIMESTAMP("2023-07-05
12:00:00"), TIMESTAMP("2023-07-06 12:00:00")),
ARRAY(date("2023-07-04"), date("2023-07-05"), date("2023-07-06"))
),
(
ARRAY(tinyint(10), tinyint(20), tinyint(30)),
ARRAY(smallint(100), smallint(200), smallint(300), smallint(400)),
ARRAY(1000, 2000, 3000),
ARRAY(bigint(1000000000000000), bigint(200000000000000),
bigint(300000000000000), bigint(400000000000000)),
ARRAY(true, true,true, true),
ARRAY(float(12.3), float(45.6), float(78.9)),
ARRAY(double(100.1), double(200.2), double(300.3)),
ARRAY("abc", "eeee", "sdads"),
ARRAY(TIMESTAMP("2023-07-02 12:00:00"), TIMESTAMP("2023-07-02
12:00:00"), TIMESTAMP("2023-07-02 12:00:00")),
ARRAY(date("2021-07-04"), date("2021-07-05"), date("2021-07-06"))
),
(
ARRAY(tinyint(1), tinyint(2), tinyint(3)),
ARRAY(smallint(10), smallint(20), smallint(30), smallint(40)),
ARRAY(100, 200, 300),
ARRAY(bigint(100000000000000), bigint(20000000000000),
bigint(30000000000000), bigint(40000000000000)),
ARRAY(true, false, true),
ARRAY(float(12.3), float(45.6), float(78.9)),
ARRAY(double(100.1), double(200.2), double(300.3)),
ARRAY("abc", "eeee", "sdads"),
ARRAY(TIMESTAMP("2023-07-02 12:00:00"), TIMESTAMP("2023-07-02
12:00:00"), TIMESTAMP("2023-07-02 12:00:00")),
ARRAY(date("2021-07-04"), date("2021-07-05"), date("2021-07-06"))
);

2. 支持分隔符的指定。
```sql
hive> show create table ywtest.cyw14;
OK
CREATE TABLE `ywtest.cyw14`(
`id` int,
`arr` array<array<int>>,
`info` int)
ROW FORMAT SERDE
'org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe'

'collection.delim'=',.',

'line.delim'='\n',
'serialization.format'='\t')

3. 支持array嵌套array.
