fix[next]: Fix default value for use_max_domain_range_on_unstructured_shift

[tehrengruber]

#2173 introduced the ability to infer the domain of all as_fieldop statically when given all connectivities at compile time instead of computing everywhere. The previous behavior to compute everywhere was meant to be configurable by specifying use_max_domain_range_on_unstructured_shift=True in the backend. This option however was falsely ignored when all set_at statements had static domains. This PR fixes that and exposes use_max_domain_range_on_unstructured_shift in the dace backend factory.
