Pavan Nikhilesh f80ae1aa9a hash: unify CRC32 selection for x86 and Arm
Merge CRC32 hash calculation public API implementation for x86 and Arm.
Select the best available CRC32 algorithm when unsupported algorithm
on a given CPU architecture is requested by an application.

Previously, if an application directly includes `rte_crc_arm64.h`
without including `rte_hash_crc.h` it will fail to compile.
