[zlib] Fix infinite loop in CRC32 intrinsics.

When building zlib with CRC enabled, such as with -march=armv8.3a,
arm_acle.h will define functions named e.g. __crc32d that calls
__builtin_arm_crc32d. However, with our macro definitions we will end
up causing the header to define functions named __builtin_arm_crc32*
that call themselves, creating an infinite loop when the intrinsic
is called. Prevent this by moving the macro definitions to after the
header inclusion.
