Add support for SF tunnel offload

Mlx5 driver only supports VF tunnel offload.
To add support for SF tunnel offload the driver needs to:
1. Add send-to-vport metadata matching rules like done for VFs.
2. Set an indirect table for SF vport, same as VF vport.

info smaller sub functions for better maintainability.

rules from esw init phase to representor load phase.
SFs could be created after esw initialized and thus the send-to-vport
meta rules would not be created for those SFs.
By moving the creation of the rules to representor load phase
we ensure creating the rules also for SFs created later.

================
Make flow steering API loosely coupled from mlx5e_priv, in a manner to
introduce more readable and maintainable modules.

Make TC's private, let mlx5e_flow_steering struct be dynamically allocated,
and introduce its API to maintain the code via setters and getters
instead of publicly exposing it.

Introduce flow steering debug macros to provide an elegant finish to the
decoupled flow steering API, where errors related to flow steering shall
be reported via them.

All flow steering related files will drop any coupling to mlx5e_priv,
instead they will get the relevant members as input. Among these,
fs_tt_redirect, fs_tc, and arfs.
