feat: auto-include synthetic link dimensions when member is included in a view

When a dimension with links is included in a view (via explicit includes
list), its synthetic link dimensions are now automatically included as
well. This mirrors how hierarchy level dimensions are auto-included.

For includes: '*', synthetic dims are already picked up since they exist
as regular dimensions on the source cube.
