Implicit parameter conversion from integer to byte fails with source generated XAML

[DJ4ddi]

Description

When using a component property of type byte, its value cannot be assigned using source generated XAML. Instead, BindableObject logs a warning.

The same property works fine with XAMLC or runtime inflation.

Steps to Reproduce

1. Create a component with a byte property:

public static readonly BindableProperty MyByteProperty = BindableProperty.Create(
  nameof(MyByte),
  typeof(byte),
  typeof(MyComponent),
  (byte)255);

public byte MyByte
{
  get => (byte)this.GetValue(MyByteProperty);
  set => this.SetValue(MyByteProperty, value);
}

2. Use the component parameter in XAML: <MyComponent MyByte="150"/>
3. Enable source generated XAML: <MauiXamlInflator>SourceGen</MauiXamlInflator>
4. Initialize the outer component.

Expected: The property should have the configured value (150 in the example).
Actual: The property always has the default value (255 in the example).
