[nexus] migrate MAC scan test to nexus (#12938)

Browse Source 
This commit migrates the 'test_mac_scan.py' cert test to the Nexus
simulation framework.

The new Nexus test 'test_mac_scan.cpp' verifies the IEEE 802.15.4
Active Scan (MAC scan) functionality. It forms a simple network
consisting of a Leader and a Router and performs an active scan
from the Leader to ensure it correctly discovers the Router's
beacon.

The original Python test script is removed as its functionality is
now fully covered by the new Nexus test.
