e3938f4d - [Offload] Detect native ELF machine from preprocessor (#91282)

[Offload] Detect native ELF machine from preprocessor (#91282) Summary: This gets the target's corresponding ELF value from the preprocessor. We use this to detect if a given ELF is compatible with the CPU offloading impolementation for OpenMP. Previously we used defitions from CMake, but this is easier for people to understand as there may be new users of this in the future.
