rG43ac5806a5a3: bridge: Divorce ifuntagged from vlanfilter

Summary

The ifuntagged option was added as part of the VLAN filtering feature,
but it's useful on its own to be able to place interface traffic in a
VLAN without having to configure every interface for VLAN filtering.

Always do the pvid processing in bridge even if IFBRF_VLANFILTER isn't
enabled, and don't prohibit configuring it.

Add a test for the specific case of setting untagged without vlanfilter.

This has no effect on bridges which don't have at least one interface
configured with ifuntagged.
