EfCoreValueConverter missing parameterless constructor

[PoolPirate]

Describe the bug

In order for the value converter to work in the HaveConversion method a parameterless constructor is needed.
Currently trying to use the converter will throw

System.InvalidOperationException: "Cannot create an instance of value converter type 'EfCoreValueConverter'. Ensure that the type can be instantiated and has a parameterless constructor, or use the overload of 'HasConversion' that accepts a delegate."

In contrast the StronglyTypedIds lib does provide a parameterless constructor in the source generated converter which does solve this issue.

Steps to reproduce

1. Install latest version of EFCore (6.0.4) and Vogen (1.0.19)
2. In the DbContext override ConfigureConventions and configure a conversion with the source generated converter.
3. Create / Apply migrations will throw

Expected behaviour

The value converter should come with a default parameterless constructor.
