Razor pages with runtime compilation enabled throw exception when creating models using the C# 11 'required' keyword

### Is there an existing issue for this?

- [X] I have searched the existing issues

### Describe the bug

When Razor runtime compilation is enabled, it is not possible to construct models that use the C# 11 `required` keyword from a razor page, though it works fine everywhere else.

Once the code is executed, the following exception is thrown:
```
Microsoft.AspNetCore.Mvc.Razor.RuntimeCompilation.CompilationFailedException: One or more compilation failures occurred:
C:\Code\Learning\RazorRequiredField\Pages\Index.cshtml(13,20): error CS0619: 'SampleModel.SampleModel()' is obsolete: 'Constructors of types with required members are not supported in this version of your compiler.'
at Microsoft.AspNetCore.Mvc.Razor.RuntimeCompilation.RuntimeViewCompiler.CompileAndEmit(RazorCodeDocument codeDocument, String generatedCode)
at Microsoft.AspNetCore.Mvc.Razor.RuntimeCompilation.RuntimeViewCompiler.CompileAndEmit(String relativePath)
at Microsoft.AspNetCore.Mvc.Razor.RuntimeCompilation.RuntimeViewCompiler.OnCacheMiss(String normalizedPath)
```

### Expected Behavior

The expected behaviour is that these new features can be used in pages, as well as anywhere else.

### Steps To Reproduce

A full example project that exhibits this behavior can be found here:
https://github.com/NinovanderMark/RazorPagesRuntimeCompilationBug

To create it from scratch, simply create a new .NET 7 Web application using Razor Pages, and enable runtime compilation like so:
```csharp
builder.Services.AddRazorPages().AddRazorRuntimeCompilation();
```
Next, add a new model which has a `required` field with. Something like this:
```csharp
public class SampleModel
{
public required string Name { get; init; }
}
```
Finally, instantiate this class from a Razor Page. Maybe we have a Method that requires it, so we call that with a newly constructed instance:
```csharp

Once the user navigates to the page that has this code, the exception will be thrown.
