Michael Paquier ae75d12b50 pg_stat_statements: Add tests for SQL/JSON query patterns ...

A new test file is added to track how the various SQL/JSON query
patterns fare in PGSS, as allowed by the parser:
- Query functions
- JSON_TABLE
- Constructors and predicates.
- etc.

This will be handy for the evaluation of some follow-up patches that aim
to tweak the query jumbling for a portion of some of these SQL/JSON
queries.  Some of them are currently slightly broken, tracking as
parameters what should be a keyword, and we never knew about them.
Until now.

The author has written most of the patch.  I have noticed a couple of
gaps and some inconsistencies upon further review, leading to a result
more consistent with the usual approach used by the PGSS tests.
