### What problem does this PR solve?
Problem Summary:
before not deal with float16 type, so it's mapping to string type, and
the result is invaild eg:
```
mysql> select * from HDFS("uri" = "hdfs://127.0.0.1:8020/user/doris/tvf_data/test_hdfs_parquet/group0/float16_nonzeros_and_nans.parquet", "hadoop.username" = "doris", "format" = "parquet");
+------+
| x |
+------+
| NULL |
| < |
| � |
| ~ |
| |
| � |
| � |
| @ |
+------+
```
but it's could mapping to float type, eg:
```
mysql> select x from file( "fs.local.support" = "true", "file_path" = "float16_nonzeros_and_nans.parquet", "format" = "parquet",'shared_storage'='true' );
+------+
| x |
+------+
| NULL |
| 1 |
| -2 |
| NaN |
| 0 |
| -1 |
| -0 |
| 2 |
+------+
```
