Consider adding a `has_flag` option to the comparison operators

Would you please consider adding a has_flag option to the comparison operators to support bitwise flags? For example, let's say one of our columns called, "ProductType" can hold a value representing one or more of the following flag values:

[Flags]
public enum ProductType
{
    Flight = 1,
    Hotel = 2,
    Tour = 4,
    Transfer = 8
    //etc 16, 32, 64...
}

So if a booking record in my database has a value of 3 for the ProductType, this means it was a Flight + Hotel booking. Now if I want to query all records where there is a hotel component (for example), then I need to produce a query as follows:

SELECT *
FROM Bookings
WHERE ProductType & 2 <> 0

Having a has_flag operator would be good here. As for UI, we could use checkboxes. If multiple values are checked, you would produce multiple WHERE clauses.

The issue names no files, tests, or entry points, so start by locating the comparison-operator definitions and the UI configuration for operators. Review how SQL conditions are generated, using the ProductType & 2 <> 0 example as the expected behavior. Done means supporting a has_flag option and defining checkbox behavior for multiple selected flags.
