mac arm64: add support for this new configuration to zlib
While compiling third_party/zlib/cpu_features.c, for example during
https://ci.chromium.org/p/chromium/builders/ci/mac-arm64/661:
../../third_party/zlib/cpu_features.c:83:13: error: unused function '_cpu_check_features' [-Werror,-Wunused-function]
static void _cpu_check_features(void)
^
macOS support for arm64 is expected to have a high baseline requirement
for extensions such as crc32, so rather than doing runtime feature
detection, assume presence. crc32 is mandatory in ARMv8.1-A per ARM DDI
0487F.b (current), and all Apple ARM A-series CPUs since A10 (2016)
implement at least ARMv8.1-A.
