Only disable legacy bridging if an existing network.device section with type
bridge is found, ignore non-type sections since those do not declare a
bridge but set attributes on top of an existing one.

The existing logic only handled removing the last remaining device section
option (which results in the deletion of the entire section) but failed to
actually unset single options.

When setting bridge and device specific options such 'stp' or
'igmp_snooping', LuCI so far transparently created or reused a
`config device` section and set the corresponding option there.
In the case of bridges, this triggers multiple problems:
- When implicitely creating a `config device` section referring to the
bridge device, the legacy bridge configuration of the corresponding
interface is disabled, causing a broken configuration on subsequent
save operations
- Netifd does not appear to properly merge bridge settings from config
device and config interface sections, leading to an incoherent
configuration state
In order to avoid that issue, do not automatically migrate bridge specific
options.

- Disable interface-level bridging if a corresponding br-$name bridge
already exists as device declaration
- Exempt wireless interfaces from bridge port configuration, they can only
be attached indirectly through "option network"
- Consider bridge ports from both "option ifname" in interface/device
sections and from "option ports" in bridge-vlan ones
- Small fixes for rendering quirks
