This commit adds support to show ANTLR parsing time info with EXPLAIN info. With this change, query plan would look like following:
```
QUERY PLAN

----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Query Text: select 'abc'

Result  (cost=0.00..0.01 rows=1 width=32) (actual time=0.004..0.005 rows=1 loops=1)

ANTLR Parsing Time: 34.469 ms

Planning Time: 0.016 ms
