G-3160 – Avoid visible virtual columns.

In contrast to visible columns, invisible columns are not part of a record defined using `%rowtype` construct. This is helpful as a virtual column may not be programmatically populated. If your virtual column is visible you have to manually define the record types used in API packages to be able to exclude them from being part of the record definition. Invisible columns may be accessed by explicitly adding them to the column list in a `select` statement.
