net/mlx5: introduce new flow counters configuration macro

The new configuration macro HAVE_IBV_DEVICE_COUNTERS_SET_V45 is
introduced. Both makefile and meson.build are changed.

Flow counter support code depends on the following configuration
macros:

- HAVE_IBV_DEVICE_COUNTERS_SET_V42 - is defined if system supports
  the "old" flow counters functionality, MLNX_OFED version from
  4.2 to 4.4 is required.

- HAVE_IBV_DEVICE_COUNTERS_SET_V45 - is defined if system supports
  the "new" flow counters functionality, MLNX_OVED 4.5 (or higher)
  or Linux rdma-core v19 (or higher) is required.

Neither HAVE_IBV_DEVICE_COUNTERS_SET_V42 nor
HAVE_IBV_DEVICE_COUNTERS_SET_V45 is defined if there is no
counters support.
