Silence IDE0290.

This rule recommends use of primary constructors. Apply the suggestions on simple POCOs, adjusting some to readonly/structs/records at the same time. For more complex classes, the use of primary constructors is more distracting than helpful, so silence the rule. IDEs can still offer fixes for using primary constructors, but it will not show up as a build issue.
