[SPARK-31904][SQL] Fix case sensitive problem of char and varchar partition columns
### What changes were proposed in this pull request?
```sql
CREATE TABLE t1(a STRING, B VARCHAR(10), C CHAR(10)) STORED AS parquet;
CREATE TABLE t2 USING parquet PARTITIONED BY (b, c) AS SELECT * FROM t1;
SELECT * FROM t2 WHERE b = 'A';
```
Above SQL throws MetaException
