Removes CPU, Sensors and Identify ModPC parts. (#66924)

Removes CPU, Sensors and Identify parts from modulra computers.
This is in effort to simplify how tablets and tablet apps are, while removing barriers to download specific apps. Limiting apps needed for your job, through hardware, is a terrible idea, and just limits departmental stuff to being there roundstart/latejoin, punishing people who job change through the in-game HoP system, devaluing the job as a whole.
