net/mlx5: Generalize Flow Context for new crypto fields
In order to support MACsec offload (and maybe some other crypto features
in the future), generalize flow action parameters / defines to be used by
crypto offlaods other than IPsec.
The following changes made:
ipsec_obj_id field at flow action context was changed to crypto_obj_id,
intreduced a new crypto_type field where IPsec is the default zero type
for backward compatibility.
Action ipsec_decrypt was changed to crypto_decrypt.
Action ipsec_encrypt was changed to crypto_encrypt.
IPsec offload code was updated accordingly for backward compatibility.
