[WifiCoex] Listen to PhysicalChannelConfigs from every sub id

PhysicalChannelConfigs may be reported for multiple sub ids
simultaneously due to modem time slicing on separate subscriptions.
Thus, TelephonyCallbacks should be registered on every sub id and the
PhysicalChannelConfigs aggregated together when calculating unsafe
channels. LAA restrictions should also only apply to channels from
sub ids with carrier config restrictions.

Bug: 184089520
Test: atest CoexManagerTest, manual verification of logs that
onPhysicalChannelConfigChanged is being called to update coex channels.
