net/mlx5: fs, add HWS packet reformat API function

Browse source 
Add packet reformat alloc and dealloc API functions to provide packet
reformat actions for steering rules.

Add HWS action pools for each of the following packet reformat types:
- decapl3: decapsulate l3 tunnel to l2
- encapl2: encapsulate l2 to tunnel l2
- encapl3: encapsulate l2 to tunnel l3
- insert_hdr: insert header

In addition cache remove header action for remove vlan header as this is
currently the only use case of remove header action in the driver.
