Rename MemberEqualityComparerAttribute to MemberEqualityComparer2Attribute

- Updated class definition from MemberEqualityComparerAttribute<T, TMember> to MemberEqualityComparer2Attribute<T, TMember>
- Updated string literal in TypeSymbolExtensions.cs source generator logic
- Updated all usage in samples and test files
- Updated obsolete attribute message to reference new name
