selftests: mlxsw: Add a scale test for RIF MAC profiles 



Query the maximum number of supported RIF MAC profiles using
devlink-resource and verify that all available MAC profiles can be utilized
and that an error is generated when user space tries to exceed this number.

Output example in Spectrum-2:

$ TESTS='rif_mac_profile' ./resource_scale.sh
TEST: 'rif_mac_profile' 4                                           [ OK ]
TEST: 'rif_mac_profile' overflow 5                                  [ OK ]

# Test for RIF MAC profiles resource. The test adds VLAN netdevices according to

# the maximum number of RIF MAC profiles, sets each of them with a random

# MAC address, and checks that eventually the number of occupied RIF MAC

# profiles equals the maximum number of RIF MAC profiles.
