WifiDiagnostics: Move logcat collection to a worker thread

Diagnostics triggered internal bugreport/alert data capture tries to
take a snapshot of logcat. This can cause the wifi thread to hang for
sometime. Since these are just used for debugging offload this operation
to a new worker thread.

Also,
i) Remove the now unused async channel thread in WifiInjector.
ii) Remove unused captureAlertData() in WifiDiagnostics.
