Categorization / general cleanup

[ducky64]

Mostly cleanup of the categorization superclasses.

Also other minor cleanup:

• Remove nonfunctional mounting holes and labels, these should be added to the layout as non-schematic footprints
  • Categorized into a new DeprecatedBlock
• Remove type from component names for IMU and magnetometer
  • Add deprecation aliases
• Add MultipackOpamp abstract block and MultipackOpampGenerator skeleton base block
• Remove switch controller and fox project test cases, those probably aren't contributing to coverage but still taking time
