Conversation
The cross build is failing due to the cpufeatures.c being compiled in. This file tries to extract cpu features using cpuid / getauxval that don't make sense to execute in the cross tools. This change disables compiling the cpufeatures.c for cross build and changes the JitGetProcessorFeatures to return zero in this case.

Backport of #91413 to release/8.0
Customer Impact
When a customer attempts to do a cross build of .NET runtime for macOS x64 on macOS arm64, the build fails during cross tools build phase. It happens due to the cpufeatures.c/h using
TARGET_XXXifdefs instead ofHOST_XXXones.Testing
Local cross build of the runtime on macOS arm64, local build on macOS x64 and local build on linux arm64.
Risk
Low, the change does not cause different CPU features being detected.
