bnxt: Update drivers to support unified UDP encapsulation offload functions

Orabug: 24567991

This patch ends up doing several things.  First it updates the driver to
make use of the new unified UDP tunnel offload notifier functions.  In
addition I updated the code so that we can work around the bits that were
checking for if VXLAN was enabled since we are now using a notifier based
setup.
