EF-76: Flow EF metadata down through CreateGetValueExpression

[ajcvickers]

That is, the IProperty or INavigation associated with the access. Types, requiredness, type-mappings, etc. are then obtained from the property.

An alias is passed in if the name in the BSON document is different from the mapped element name for the property.

Pull Request Overview

This PR refactors the CreateGetValueExpression method to flow Entity Framework metadata (properties and navigations) down through the expression tree instead of relying solely on string names and separate type information. The changes consolidate metadata handling by passing IProperty or INavigation objects directly, allowing type mappings, requiredness, and other attributes to be derived from the metadata rather than passed separately.

Key changes include:

• Simplified CreateGetValueExpression method signature to accept IPropertyBase instead of multiple separate parameters
• Updated method calls throughout the codebase to pass null as the new alias parameter
• Enhanced error messages and metadata access patterns
