Jamil 67b4dd86ea fix(apple): increase sensitivity of network reset (#9993) ...

On Apple platforms, we tried to be clever about filtering path updates
from the network connectivity change monitor, because there can be a
flurry of them upon waking from sleep or network roaming.

However, because of this, we had a bug that could occur in certain
situations (such as waking from sleep) where we could effectively "land"
on an empty DNS resolver list. This could happen if:


1. We receive a path update handler that meaningfully changes
connectivity, but its `supportsDNS` property is `false`. This means it
hasn't received any resolvers from DHCP yet. We would then setDns with
an empty resolver list.
2. We then receive a path update handler with the _only_ change being
`supportDNS=true`. Since we didn't count this change as a meaningful
path change, we skipped the `setDns` call, and connlib would be stuck
without DNS resolution.

To fix the above, we stop trying to be clever about connectivity
changes, and just use `oldPath != path`. That will increase reset a bit,
but it will now handle other edge cases such as an IP address changing
on the primary interface, any other interfaces change, and the like.

Fixes #9866
