DO NOT MERGE Fix setting hidden api usage log sample rate

This fix addresses two related issues: one with the
DeviceConfig.onPropertiesChangedListener, and another with
HiddenApiUsageLogger.setHiddenApiAccessLogSampleRates.
In both cases, setting one of the sample rates
(hidden_api_access_log_sampling_rate or
hidden_api_access_statslog_sampling_rate) unsets the other. This is due
to them being sent sequentially instead of simultaneously.
Additionally, out of an abundance of caution, mirror the behaviour in
attemptConnectionToPrimaryZygote and attemptConnectionToSecondaryZygote
for the statslog sample rate. This was overlooked in a previous change.
