resolve equivalent join hints like `TIDB_INLJ` and `INL_JOIN` when building `ID` of bindings

[eurekaka]

Development Task

For these bind_sqls:

• select /*+ tidb_inlj(t1, t2) */ * from t1, t2 where t1.a = t2.a
• select /*+ inl_join(t1, t2) */ * from t1, t2 where t1.a = t2.a

They are same actually but they have different ID now. This applies to other join hints that have aliases. Resolve them when building ID of bindings, to avoid potential duplicate bindings in mysql.bind_info.
