* [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
