* [fix](load) in strict mode, return error for load and insert if datatype convert fails
Revert "[fix](MySQL) the way Doris handles boolean type is consistent with MySQL (#19416)"
This reverts commit 68eb420cabe5b26b09d6d4a2724ae12699bdee87.
Since it changed other behaviours, e.g. in strict mode insert into t_int values ("a"),
it will result 0 is inserted into table, but it should return error instead.
* fix be ut
* fix regression tests
1. Make sure all sub types which STRUCT supported work correctly;
2. remove unused variable `_need_validate_data`;
3. lazy init min or max decimal to support nested DecimalV2 column validate;

Support running transactional insert operation with new scan framework. eg:
admin set frontend config("enable_new_load_scan_node" = "true");
begin;
insert into tbl1 values(1,2);
insert into tbl1 values(3,4);
insert into tbl1 values(5,6);

Add some limitation to transactional insert
Do not support non-literal value in insert stmt
Fix some issue about array type:
Forbid cast other non-array type to NESTED array type, it may cause BE crash.
Add getStringValueForArray() method for Expr, to get valid string-formatted array type value.
Add useLocalSessionState=true in regression-test jdbc url
without this config, the jdbc driver will send some init cmd each time it connect to server, such as
select @@session.tx_read_only.
But when we use transactional insert, after begin command, Doris do not support any other type of
stmt except for insert, commit or rollback.
So adding this config to let the jdbc NOT send cmd when connecting.
