net/mlx5e: Add flow rules for the decrypted ESP packets

The previous commit introduced two new flow groups to enable L4 RSS
for decrypted IPsec traffic. This commit implements the logic to
populate these groups with the necessary steering rules.

The rules are created dynamically whenever the first IPSec offload
rule is configured via the xfrm subsystem and the decryption tables
for RX are created. Each rule matches a specific decrypted traffic
type based on its ip version (or ethertype) and outer/inner
l4_type_ext, directing it to the appropriate L4 RSS-enabled TIR.

The lifecycle of these steering rules is tied directly to the RX
tables. They are deleted when the RX tables are destroyed.
