target-arm: Add support for AArch32 ARMv8 CRC32 instructions
Add support for AArch32 CRC32 and CRC32C instructions added in ARMv8 and add a CPU feature flag to enable these instructions. The CRC32-C implementation used is the built-in qemu implementation and The CRC-32 implementation is from zlib. This requires adding zlib to LIBS to ensure it is linked for the linux-user binary.
