typecd: Add UdevMonitor support for Cable alt modes

Update UdevMonitor (and as a result of the observer change, PortManager
too) to respond to Cable (i.e SOP' plug) alt mode registration events.

Also update the UdevMonitor unit tests to:
- Include cable addition during the hotplug test
- Add a new test to validate cable plug alt mode addition.

BUG=b:172097194
TEST=Ensure that typecd unit tests still pass.
