Add UseDefaultOnConversionFailure to DefaultAttribute

[leftiness]

Is your feature request related to a problem? Please describe.

There is no provided attribute to set UseDefaultOnConversionFailure.

Describe the solution you'd like

I want to set UseDefaultOnConversionFailure=true as part of the DefaultAttribute. The value should be false by default.

Describe alternatives you've considered

• I could use a ClassMap
• You could implement a UseDefaultOnConversionFailureAttribute
• I could implement my own attribute

Additional context

example

public class User
{
    [Default("leftiness", UseDefaultOnConversionFailure = true)]
    public string Username { get; set; }
}
