IB/mlx5: Refactor UMR post send format
* Update struct mlx5_wqe_umr_ctrl_seg. * Currenlty UMR send_flags aim only certain use cases: enabled/disable cached MR, modifying XLT for ODP. By making flags independent make UMR more flexible allowing arbitrary manipulations. * Since different UMR formats have different entry sizes UMR request should receive exact size of translation table update instead of number of entries. Rename field npages to xlt_size in struct mlx5_umr_wr and update relevant code accordingly. * Add support of length64 bit.
