Backport of #83888 to release/8.0-preview3
/cc @jandupej
Customer Impact
SIMD on mono, JIT, arm64 platforms is to be fully disabled until all intrinsics are implemented and fully tested. Operator intrinsics inadvertently remained enabled, potentially causing issues to customers. This PR disables all SIMD intrinsics on arm64, JIT.
Testing
Manual testing. Additionally there should be no CI failures involving
System.Numerics.Vectors.Testson arm64 platforms.Risk
Low. The PR disables features in favor of preexisting, well tested fallbacks.
IMPORTANT: Is this backport for a servicing release? If so and this change touches code that ships in a NuGet package, please make certain that you have added any necessary package authoring and gotten it explicitly reviewed.
