pg_stat_statements: Add tests with extended query protocol

Browse Source 
There are currently no tests in the tree checking that queries using the
extended query protocol are able to map with their query ID.

This can be achieved for some paths of the extended query protocol with
the psql meta-commands \bind or \bind_named, so let's add some tests
based on both.

I have found that to be a useful addition while working on a different
issue.
