net/mlx5: add flow jump action

Jump action connects different level of flow tables and allows packet
handling in the chain of flows.

A new action construct data struct is also added in this commit to help
to handle not only the dynamic jump action but also for the other
generic dynamic actions. The actions with empty mask configuration means
dynamic action, and the dedicated action will be created with the flow
action configuration during flow creation. In that dynamic action case,
the action will be appended to the table template's action list during
table creation.
When creating the flows, traverse the action list and pick the dynamic
action configuration details from flow actions as the action construct
data struct describes, then create the dedicated dynamic actions.

This commit adds the jump action and the generic dynamic action
construct mechanism.
