Add model-specific filters for cables

Proposed functionality

Add the following query filters for cables:

• circuittermination
• consoleport
• consoleserverport
• frontport
• interface
• powerfeed
• poweroutlet
• powerport
• rearport

These filters can be used to easily filter for cables by their terminating object(s). For example, GET /api/dcim/cables/?interface=123 will return the cable (if any) terminated to the interface with ID 123.

It should be possible to pass multiple values effecting a logical OR, to allow returning all cables attached to any of the specified terminations, e.g. GET /api/dcim/cables/?interface=123&interface=456&frontport=789.

Use case

This approach greatly simplifies filtering of cables by specific termination points. As noted in #14274, the current approach utilizing termination_type and termination_id filters is limited and error-prone.
