also not clear to me what the rationale here is. I don't believe `arm_emulator_executable` was intended to mean run all the integration tests under emulation, it was intended to support running the integration tests for ISAs like SVE and SME enabled under
- MLIR_RUN_ARM_SVE_TESTS
- MLIR_RUN_ARM_SME_TESTS

where hardware isn't yet widely available. I think we need to mindful here because this will mean these tests are unnecessarily run under emulation on AArch64 hosts and will take longer to run.
