Closes #23031: Add 8C1P, 12C1P, and 24C1P trunk cable profiles

Introduce trunk profiles with eight, twelve, and twenty-four single-position
connectors at each end, for multi-strand fiber cables spliced to individual
pigtails within patch panels. Add the profile choices, register the profile
classes, and test link peer resolution for each.
