Add `DateOnly` and `TimeOnly` string query parameter support

[maxkoshevoi]

Describe the bug

DateOnly and TimeOnly should be represented as a string value when passed from a query (similar to DateTime's behavior).

To Reproduce

• Create an api action with following parameters public void Foo([FromQuery] DateOnly date, [FromQuery] TimeOnly time, [FromQuery] DateTime dateTime).
• See what arguments it expects.

Expected result

I can pass date and time as two string values (similar to how I can pass dateTime as a string).

Actual result

I need to specify all DateOnly and TimeOnly properties individually (see screenshot above)

Further technical details

• ASP.NET Core .NET 6 RC1
• IDE: VS 2022 Preview 4.0

Workaround

• Custom model binder + Swagger configuration
• Custom type converter (Swagger will see it automatically). https://github.com/maxkoshevoi/DateOnlyTimeOnly.AspNet/tree/main/DateOnlyTimeOnly.AspNet/Converters/Type
