Support 'UniqueContentTypeFieldsOrderDefinition' at list level content types

[SubPointSupport]

Is it possible with M2 to change the column order for a list? I'm looking for something similar to ".UniqueContentTypeFieldsOrderDefinition()" but for lists which dosen't have content types enabled. For some reason the fields I'm provisioning is not placed in the same order which they were provisioned in.

Essentially, it comes back to the default content type in a list.

The default content type is responsible for the column order within a list while content types are disables. Document for the doc libraries, Item for the custom lists, and so on.

M2 does not support list scoped content type operations, so it would require more effort and new feature set.

ContenTypeLink now supports .AddUniqueContentTypeFieldsOrder() syntax, so that the target content type within a list can be resolved and updated with the desired field order.

Works well on custom and OOTB content type for both CSOM/SSOM. Below tests can be used as a jump start.
