Error codes for hardware accelerator failures
Add MBEDTLS_ERR_XXX_HW_ACCEL_FAILED error codes for all cryptography modules where the software implementation can be replaced by a hardware implementation. This does not include the individual message digest modules since they currently have no way to return error codes. This does include the higher-level md, cipher and pk modules since alternative implementations and even algorithms can be plugged in at runtime.
