[Enhancement](tvf) Table value function support reading local file (#17404)

I tested the local tvf with tpch queries. First, generate `lineitem` datasets with 6001215 rows, and load it into `lineitem` table by:
```
insert into lineitem select c11, c1, c4, c2, c3, c5, c6, c7, c8, c9, c10, c12, c13, c14, c15, c16 
from local(
        "file_path" = "tools/tpch-tools/bin/tpch-data/lineitem.tbl.1", 
        "backend_id" = "10003", 
        "format" = "csv", 
        "column_separator" = "|"
);
```
Then, run `q1` and `q16` tpch queries, the query result is correct.

It can also analyze the BE's log directly like:

```
mysql> select * from local(
        "file_path" = "log/be.out",
        "backend_id" = "10006",
        "format" = "csv")
       where c1 like "%start_time%" limit 10;
