feat: add Register to property setup

[vbreuss]

This PR adds a Register() method to the property setup API, allowing properties to be registered without specifying a value. This is particularly useful when using MockBehavior.ThrowWhenNotSetup, as it enables properties to be marked as "setup" without defining specific behavior, preventing MockNotSetupException from being thrown when the property is accessed.

Key changes

• Added Register() method to IPropertySetup<T> interface with XML documentation
• Implemented Register() in PropertySetup<T> class (returns this for fluent chaining)
• Added comprehensive tests validating both the exception scenario without registration and successful registration behavior
