use StringRef instead of string_view operator == for vectorized impl for array_contains function.
- test data: 10,000,000 rows with a ARRAY<STRING> column. There are 10 elements, average length 11 chars, in the array column in each row.
- test SQL: `select count() from test_like_array where array_contains(s_arr, 'xxxxxxxx');`
- test result: 0.76 sec vs. 0.52 sec, 30% time reduced
This commit support:
1、Insert + select for struct/map type
2、Json stream load for struct type
3、m[key] function for map type
How to use:
Set the fe config to create table for struct and map type
1、admin set frontend config("enable_struct_type" = "true");
2、admin set frontend config("enable_map_type" = "true");

in the previous, the result is:
```
mysql> select array_position([1, null], null);
+--------------------------------------+
| array_position(ARRAY(1, NULL), NULL) |
+--------------------------------------+
| NULL |
+--------------------------------------+
1 row in set (0.02 sec)
```
but after this commit, the result become:
```
mysql> select array_position([1, null], null);
+--------------------------------------+
| array_position(ARRAY(1, NULL), NULL) |
+--------------------------------------+
| 2 |
+--------------------------------------+
1 row in set (0.02 sec)
```
From now, we don't support type derivation for array function's arguments.
So that the cases below will return wrong values or even cause be core.
mysql> select array_union([1],[10000000]);
+----------------------------------------+
| array_union(ARRAY(1), ARRAY(10000000)) |
+----------------------------------------+
| [1, -128] |
+----------------------------------------+
1 row in set (0.03 sec)
mysql> select array_union([NULL],[1]);
ERROR 1105 (HY000): RpcException, msg: io.grpc.StatusRuntimeException: UNAVAILABLE: Network closed for unknown reason
mysql> select array_union([],[1]);
ERROR 1105 (HY000): RpcException, msg: io.grpc.StatusRuntimeException: UNAVAILABLE: Network closed for unknown reason
This commit make a small fix to derivate the argument types of the array function
1、 For null type in arguments, cast the null type to boolean type, because null type should not be seen in be.
2、For different types in arguments, cast all arguments type to their compatible type.
this pr is used to fix the wrong result of array_join function.
before the change, the array_join function will return wrong result.
MySQL [example_db]> select array_join(["", "1", "2"], '');
+--------------------------------------+
| array_join(ARRAY('', '1', '2'), '') |
+--------------------------------------+
| 1_2 |
+--------------------------------------+
3.after the change, the array_join function will return correct result.
MySQL [example_db]> select array_join(["", "1", "2"], '');
+--------------------------------------+
| array_join(ARRAY('', '1', '2'), '') |
+--------------------------------------+
| _1_2 |
+--------------------------------------+
Issue Number: #7570
# Proposed changes
This PR fixed lots of issues when building from source on macOS with Apple M1 chip.
## ATTENTION
The job for supporting macOS with Apple M1 chip is too big and there are lots of unresolved issues during runtime:
1. Some errors with memory tracker occur when BE (RELEASE) starts.
2. Some UT cases fail.
...
Temporarily, the following changes are made on macOS to start BE successfully.
1. Disable memory tracker.
2. Use tcmalloc instead of jemalloc.
This PR kicks off the job. Guys who are interested in this job can continue to fix these runtime issues.
## Use case
```shell
./build.sh -j 8 --be --clean
cd output/be/bin
ulimit -n 60000
./start_be.sh --daemon
```
## Something else
It takes around _**10+**_ minutes to build BE (with prebuilt third-parties) on macOS with M1 chip. We will improve the development experience on macOS greatly when we finish the adaptation job.
This pr is used to expand the supported data type for array_min/array_max function.
Before the change , the array_min/array_max function can't support the date/datetime type.
After the change, array_min/array_max function can support the date/datetime type.

In old Doris version string offsets are 32bit, but it is not enough for Array type.
If we change string offsets from 32bit to 64bit, there will be problem if we upgrade BE one by one. Because at the same time 32bit Offsets and 64 bit Offsets String will exist at the same time.
As a result, we separate the Codes for Array Offsets.
