selftests: drv-net: Add test for cross-esw rate scheduling

Adds a Python selftest using the YNL devlink API to verify the devlink
rate ops. The test requires a bond device given in the config as NETIF
containing two PFs. Test setup will then create 1 VF on each PF and
verify the various rate commands.

./devlink_rate_cross_esw.py
TAP version 13
1..3
ok 1 devlink_rate_cross_esw.test_same_esw_parent
ok 2 devlink_rate_cross_esw.test_cross_esw_parent
ok 3 devlink_rate_cross_esw.test_tx_rates_on_cross_esw

Tests will be skipped when the preconditions aren't met, when the
devlink API is too old or when the devices don't appear to support
cross-esw scheduling (detected via EOPNOTSUPP).
