configs: enable CONFIG_BRIDGE_VLAN_FILTERING #6275
Description
Describe the bug
This has been asked before on the forums (https://forums.raspberrypi.com/viewtopic.php?t=341675) but not here yet.
Debian/Ubuntu have CONFIG_BRIDGE_VLAN_FILTERING enabled with CONFIG_VLAN_8021q configured as a loadable module, so we could do the same (and 8021q is already setup to be a loadable module).
Enabling this would only slightly increase the uncompressed kernel size, but would allow bridges to be automatically network aware, which isn't the case at the moment.
Steps to reproduce the behaviour
Install Raspberry Pi OS, do grep VLAN_FILTERING /boot/config*.
Result is #CONFIG_BRIDGE_VLAN_FILTERING is not set for every kernel config file.
