Add bitmasks to ttc_params to indicate if rule is valid or not.
It will allow to create TTC table with support only in part of the
traffic types.
In later patches which introduce the steering based LAG port selection,
TTC will be created with only part of the rules according to the hash
type.

Introduce new APIs to create and destroy flow matcher
for given format id.
Flow match definer object is used for defining the fields and
mask used for the hash calculation. User should mask the desired
fields like done in the match criteria.
This object is assigned to flow group of type hash. In this flow
group type, packets lookup is done based on the hash result.
This patch also adds the required bits to create such flow group.

Generate a traffic type bitmap that will define which
steering objects we need to create for the steering
based LAG.
Bits in this bitmap are set according to the LAG hash type.
In addition, have a field that indicate if the lag is in encap
mode or not.

Every definer will consist of a flow table with a single hash group
with exactly two flow table entries, one for each device port.
The destination of these entries is the uplink vport according to the
port state and hash policy.

Add create function, build the steering tables, TTC and definers
according to the LAG hash type.
The destroy function, destroys all the steering components.
The modify functions is used when the bond mapping changes and it
iterates over all the rules in the definers and modifies them to steer
the packet to the relevant active ports.

Use dynamic allocation for the dest array in preparation for
the next patch which increase MLX5_MAX_FLOW_FWD_VPORTS and
will cause stack allocation to be bigger than 1024 bytes.
