Fix GH-11785: '++nothing+crc' is not a recognized feature for M1 / M2 macOS compile target (#11796)

#pragma GCC target("+nothing+crc") is means clear outs aarch64_isa_flags.

However, #pragma clang attribute push(__attribute__((target("+nothing+crc") is not means any, then displays ignore feature. (Not reproduce Linux on ARM (ex: Raspberry Pi))

Therefore, Add new #pragma when compiling on M1/M2 macOS.
