feat(a32nx): accurate altimetry and split baro corrections

[tracernz]

Fixes #6717
Fixes #8397
Fixes #9649
Fixes #9507

Summary of Changes

• Implement accurate altimetry computations from static pressure.
• Split EIS baro corrections between captain and first officer side.
• Increased available baro correction range to 745-1100 hPa.
• Add baro ref and altitude discrepancy FWC warnings.
• Add CHECK ALT message on PFD.
• Fixed the A380X to the extent necessary for everything to still work, and extended the baro range to 745-1100 hPa. We cannot split the baro corrections here due to the 3D model, but plenty of prep work is done.

The MSFS altimeters are now allocated as follows (for the benefit of third parties, the ISIS (for now...), and a few systems that need fixed):

• 1: captain side
• 2: first officer side
• 3: ISIS (will need 2 of these eventually in A380X)...
• 4: legacy/deprecated "autopilot" pressure altitude altimeter, to be deleted in the future.

Testing instructions

Perform full flights and look out for any altitude errors. Cross-check with the ISIS.
Perform failure scenarios of FCUs, ADRs. #9658 should merge first before these tests.

Code looks very good to me, did not perform a very in depth review as it's quite extensive. But overall LGTM. Fix the rust tests and we can get this tested :)
