net/mlx5: DR, Support IPv4 and IPv6 mixed matcher

Until now SW steering supported matchers that are IPv4 and IPv6.
The limitation was mixed matchers in which the outer header IP version
was different from the inner header IP version.

To support the mixed matcher we create all the possible ste_builder
combinations, once we create a rule we select the correct one to
be used for rule creation.

net/mlx5: DR, Allow insertion of duplicate rules

Duplicate rules were not allowed to be configured with SW steering.
This restriction caused failures with the replace rule logic done by
upper layers.

This fix allows for multiple rules with the same match values, in
such case the first inserted rules will match.

net/mlx5: DR, Fix getting incorrect prev node in ste_free

When we free an STE and the STE is in the middle of collision
list, the prev_ste was obtained incorrectly from the list.
To avoid such issues list_entry calls replaced with standard list API.

net/mlx5: DR, Expose steering rule functionality

Rules are the actual objects that tie matchers, header values and
actions. Each rule belongs to a matcher, which can hold multiple rules
sharing the same mask. Each rule is a specific set of values and
actions.
When a packet reaches a matcher it is being matched against the
matcher`s rules. In case of a match over a rule its actions will be
executed. Each rule object contains a set of STEs, where each STE is a
definition of match values and actions defined by the rule.
This file handles the rule operations and processing.
