this gets altitude and EAS2TAS much more accurately up to around 150k feet AMSL. Enabled on boards using EKF double

useful as GPS comparison
this uses the stored value calculated once per loop
and improve pitot handling
this test completed at 59s before the baro change, and needs 62s afterwards with the slight change in atmospheric modelling increase to 70s so it doesn't flap

this replaces PR #17984
the formula in this PR are from @hendjoshsr71 who re-worked my original PR to use a parametric system instead of a full table
the use of the new formula is only enabled if EKF double precision is enabled or building for SITL
