Normalise fields compared to values

Applies to ✅ Open Source Edition   ✅ Express Edition   ✅ Professional Edition   ✅ Enterprise Edition

When comparing column expressions with values, the various pattern replacements profit from a simplification where we normalise the order of operands to have the value on the right side of the operator.

Using Settings.transformPatternsNormaliseFieldCompareValue, the following transformations can be achieved:

-- With Settings.transformPatternsNormaliseFieldCompareValue active, this:
SELECT * FROM tab WHERE 1 = a;

-- ... is transformed into the equivalent expression:
SELECT * FROM tab WHERE a = 1;
