[beego-orm]Support Like binary

The following two statements illustrate that string comparisons are not case sensitive unless one of the operands is a case sensitive (uses a case-sensitive collation or is a binary string):

mysql> SELECT 'abc' LIKE 'ABC';
-> 1
mysql> SELECT 'abc' LIKE _latin1 'ABC' COLLATE latin1_general_cs;
-> 0
mysql> SELECT 'abc' LIKE _latin1 'ABC' COLLATE latin1_bin;
-> 0
mysql> SELECT 'abc' LIKE BINARY 'ABC';
-> 0

The syntax described here works in TiDB with the limitation that TiDB does not yet support case-insensitive collations. Since there is an existing issue open for case sensitive collations, I am going to close this issue for now.

Please feel free to re-open if you have any followup questions. Thanks!
