T7664: ip protocol 'kernel' etc removed

In FRR 10.5 ip protocols

* connected
* kernel
* local
* table
* table-direct

are removed. First three in fb8e399e4f66d09780f176fbecb99168089e64eb,
table* in 7fd030504be060387694e8a2af7f19ddd7dee39d.

In `ip protocols`, `ipv6 protocols` and `vrf`  VyOS supports

* connected
* kernel
* table

Remove these from CLI, add migration scripts, update tests.
