NET8 ResourceManagerStringLocalizerFactory not Work In ALC

### Is there an existing issue for this?

- [X] I have searched the existing issues

### Describe the bug

Create method in source code
```
public IStringLocalizer Create(Type resourceSource)
{
Microsoft.AspNetCore.Shared.ArgumentNullThrowHelper.ThrowIfNull(resourceSource, "resourceSource");
if (!_localizerCache.TryGetValue(resourceSource.AssemblyQualifiedName, out var value))
{
TypeInfo typeInfo = resourceSource.GetTypeInfo();
string resourcePrefix = GetResourcePrefix(typeInfo);
Assembly assembly = typeInfo.Assembly;
value = CreateResourceManagerStringLocalizer(assembly, resourcePrefix);
_localizerCache[resourceSource.AssemblyQualifiedName] = value;
}

return value;
}
```
You can see that the cache key is Type AssemblyQualifiedName, however, in ALC, after hot overloading, AssemblyQualifiedName may still be consistent.
The Type handle, Type resource, and so on have changed after hot overloading, which makes it impossible for me to obtain resource information after hot overloading

### Expected Behavior

I hope to change it to a virtual method, which can be customized by users

### Steps To Reproduce

_No response_

### Exceptions (if any)

_No response_

### .NET Version

8.0.202

### Anything else?

_No response_

Start at ResourceManagerStringLocalizerFactory.Create(Type resourceSource) and inspect how _localizerCache uses AssemblyQualifiedName when types are loaded in an ALC. Reproduce the .NET 8.0.202 hot-overloading scenario if possible; done means the factory supports the requested user customization and resource lookup remains usable after the type changes.
