This commit implements the mlx5_flow_os_create_flow_matcher() API. It is
the Linux rdma-core equivalent implementation. Missing rdma-core
parameters (e.g. struct mlx5dv_flow_match_parameters) are added to file
mlx5_win_defs.h. The API allocates space to hold the PRM bits in PRM
fte_match_param format and copy the DV translated PRM bits into the
matcher struct. This matcher struct will be used later by the flow
creation API.
