fix(a380x/fctl): Protection speeds improvements after flight model update

[flogross89]

Fixes #9689
Fixes #8725

Summary of Changes

• Adapted zero lift alpha to MSFS flight model values:
  
• Adapt alpha max and alpha prot values to match existing references
• Fix high speed protection green double bar in PFD
• Fix protection markers in PFD (and add simplified FCDC in the process)
• Fix VMAX / VfeNext for CONF 1+F and CONF 1

Additional context

Note for reviewer: Only alpha max and alpha protection look-up tables were modified in the MATLAB models, no MATLAB review needed.

Testing instructions

1. Verify protection markers (pitch&roll, overspeed) show correctly in PFD in normal and in direct law (disable all PRIMs for that)
2. Fly around, try to match PFD protection speeds to known references and report where they deviate
3. Even without looking at references, the aircraft should perform reasonably, e.g. shouldn't activate protections at green dot speed in clean conf in standard turns.
