meta-google: gbmc-ncsi-config: Migrate to common RA handler

This gets rid of our bespoke RA handling code and uses the common RA
code for both RA processes on the NCSI port.

Tested: Ran on a NCSI CN and verified that RAs are still parsed and the
addresses / hostname can still be found with the smartnic WA executed.
