[mono] Failing runtime JIT/SIMD/Vector3Interop_r/ro tests on osx-arm64.

Failures in JIT/SIMD/Vector3Interop_r/ro on osx-arm64 with miniJIT and interpreter.

The same tests are passing on runtime osx-x64 miniJIT/interpreter and linux-arm64 miniJIT CI pipelines.

Could be related to Mono missing support for passing Vectors in SIMD registers (#60068) and/or missing intrinsics support for System.Numerics.Vector3 (#81501).

No longer failing on osx-arm64 miniJIT after #96079.
