selftests: mlxsw: Add a TBF selftest
Add a test that runs traffic across a port throttled with TBF. The test checks that the observed throughput is within +-5% from the installed shaper. To allow checking both the software datapath and the offloaded one, make the test suitable for inclusion from driver-specific wrapper. Introduce such wrappers for mlxsw.

# This test sends a stream of traffic from H1 through a switch, to H2. On the

# egress port from the switch ($swp2), a shaper is installed. The test verifies

# In order to test per-class shaping, $swp2 actually contains TBF under PRIO or
