net/mlx5e: CT: Add support for hardware steering

This series start with one more HWS patch by Yevgeny, followed by
patches that add support for connection tracking in hardware steering
mode. It consists of:
- patch #2 hooks up the CT ops for the new mode in the right places.
- patch #3 moves a function into a common file, so it can be reused.
- patch #4 uses the HWS API to implement connection tracking.

The main advantage of hardware steering compared to software steering is
vastly improved performance when adding/removing/updating rules.  Using
the T-Rex traffic generator to initiate multi-million UDP flows per
second, a kernel running with these patches was able to offload ~600K
unique UDP flows per second, a number around ~7x larger than software
steering was able to achieve on the same hardware (256-thread AMD EPYC,
512 GB RAM, ConnectX 7 b2b).
