fix: Changing A380X LVar units used in fadec to Number

[frankkopp]

Summary of Changes

Changes the units for LVars used in the fadec rewrite to "Number" and fixing all related usages of these vars.

Also changes A32NX and A380X turbine rotation animation behavior XML to use unit Number.

In general the team has decided to only use "Number" for LVars going forward and refactor existing non-number LVars at a later point in time.

Testing instructions

A32NX: Check turbine rotation animation for different N1 - best visible when starting or shutting down. Compare to current master to see if improved

A380X Check the Fadec related systems:

• EWD / SD
  • Thrust Limits
  • N1-3 values
  • FF values
  • Oil qty
  • ...
• other systems depending on these values - e.g. VNAV might use thrust limits, etc.

Check turbine rotation animation for different N1 - best visible when starting or shutting down.

This best tested together with other current PRs in the exp branch (@flogross89)
