sql-parser Support standard UNION/INTERSECT syntax

The SQL standard allows parentheses around all query expressions (SELECTs) in a UNION. The Bison parser cannot currently handle queries like (SELECT 1) UNION (SELECT 1), let alone ((SELECT 1) UNION (SELECT 1)).

Just approved to run the actions, I will review your PR in the next week. I noticed that the gcc-6 stage fails because manually cloning does not work with forked repositories, I will see if I can provide a fix for that.

Thanks a lot. Since you're on it, I removed to last commit where I was trying to fix that issue, not doing a very good job at it.

Hi @dinodork, we currently lack the time to review this PR properly. We would like to merge it, but not without proper reviewing and that might take some more time. Please bear with us.

Hi @dinodork, this PR takes a much higher toll on my brain than anticipated. I am not sure I will be able to properly review it as I am myself not very familiar with parsing.

I just wanted to let you know that we might not be able to merge this PR.
