Add function that compares UDS Pubs in DICE chains
Adding a test to VtsRemotelyProvisionedComponentTests.cpp that checks
whether the root certificate's public key (UDS_pub) in the DICE chains
for RKP VM ("avf") and the primary KeyMint instance ("default").
Test: m libhwtrust_cxx
atest libkeymint_remote_prov_support_test
