refactor(driver-abcip): extract AbCipDriverOptions to .Contracts

Move AbCipDriverOptions (and AbCipDataType enum) to a new
Driver.AbCip.Contracts sibling project. AbCipDataTypeExtensions
(which uses DriverDataType from Core.Abstractions) stays in the
runtime driver as AbCipDataTypeExtensions.cs.

Replace two doc-comment <see cref="Core.Abstractions.IAlarmSource"/>
and <see cref="Core.Abstractions.IHostConnectivityProbe"/> with <c>X</c>
per the approved decision — no compilable using was present.

The runtime Driver.AbCip project gains a ProjectReference to .Contracts;
the .slnx is updated accordingly.
