Revise drop down groupings for cable types

[pmsharp2]

NetBox version

v.4.3.3

Feature type

Change to existing functionality

Proposed functionality

Breaking out from the feature request: #19801 to support multiple new types of coaxial cable by adding additional organization of the cable types drop down.

Current grouping:
copper
Fiber

Suggested grouping:
copper|ethernet
copper|coaxial
copper|other
fiber|multimode
fiber|singlemode
fiber|other
other

Use case

This is really just a readability option, breaking copper cables into types of copper, and fiber into types of fiber.

We might need to tweak the groups somewhat, but I've opened this for volunteers.
