executor: fix the bug: can not join if join keys are type bigint and type bit

[Enochack]

What problem does this PR solve?

Issue Number: close #11896

Problem Summary:

What is changed and how it works?

Proposal: xxx

What's Changed:

Only if integers have no unsigned flag and are negative, treat them as signed integers. Otherwise, just treat them as unsigned numbers so that the comparison between an integer and a bit set will be as expected.

How it Works:

tidb [test]> drop table if exists t;
Query OK, 0 rows affected (0.02 sec)

tidb [test]> drop table if exists t1;
Query OK, 0 rows affected (0.01 sec)

tidb [test]> create table t(c1 bigint);
Query OK, 0 rows affected (0.01 sec)

tidb [test]> create table t1(c1 bit(64));
Query OK, 0 rows affected (0.00 sec)

tidb [test]> insert into t value(1);
Query OK, 1 row affected (0.00 sec)

tidb [test]> insert into t1 value(1);
Query OK, 1 row affected (0.00 sec)

tidb [test]> select * from t, t1 where t.c1 = t1.c1;
+------+--------------------+
| c1   | c1                 |
+------+--------------------+
|    1 | 0x0000000000000001 |
+------+--------------------+
1 row in set (0.00 sec)
