Add missing features to non x86/x64 platforms

[michaelgsharp]

We need to add the features that work on x86/x64 to the other architectures. This will be done based on what users want to use on other platforms on a priority basis. This issue will be updated as more things are ecountered.

• CpuMathNative:

  machinelearning/src/Microsoft.ML.CpuMath/FactorizationMachine/FactorizationMachineInterface.netcoreapp.cs

  Lines 33 to 36 in 1b3cb77

  	if (Avx.IsSupported)
  	AvxIntrinsics.CalculateIntermediateVariables(pf, pi, px, pw, Ptr(latentWeights, pv), Ptr(latentSum, pq), pr, fieldCount, latentDim, count);
  	else
  	CalculateIntermediateVariablesNative(fieldCount, latentDim, count, pf, pi, px, pw, Ptr(latentWeights, pv), Ptr(latentSum, pq), pr);

CpuMathNative support seems still missing, any plan to add it in the future?

This is still an issue in 2026... is there any plan to add support for architectures other than x86/x64?
