net/mlx5: DR, use the right action structs for STEv3

Some actions in ConnectX-8 (STEv3) have different structure,
and they are handled separately in ste_ctx_v3.
This separate handling was missing two actions: INSERT_HDR
and REMOVE_HDR, which broke SWS for Linux Bridge.
This patch resolves the issue by introducing dedicated
callbacks for the insert and remove header functions,
with version-specific implementations for each STE variant.
