feat: Implement Slats Flaps Control Computer

[omryg2]

Summary of Changes

This PR will aim to fully implement the SFCCs functionalities.

After reading more material, the current implementation (done by yours truly) is very poor, and will not allow for easy and proper integration of failures. Hence, the entire SFCC implementation is overhauled, going to higher resolution within the computers.

• [ ] SFCC features
  • [ ] Implement Flaps channel and Slats channel
  • [x] Implement Alpha lock
  • [ ] Connect to electricity
  • [ ] Read FPPU signal from hydraulics
  • [ ] Send movement signal to hydraulics
• [x] Allow for two independent SFCCs
• [ ] Make preparations for interfacing with other systems

Should this PR be closed if work is being done on #7632?

@wpine215 Really up to you. I don't have privileges to do that

@Eagle941 is this still being worked on?

I think https://github.com/flybywiresim/aircraft/pull/7632 is the continuation.
