resourcemanagerservice: make a copy of client config

The cases when the codec is release without stopping, the
resource manager calls notifyClientStopped from notifyClientReleased.
But while doing so, it passes a reference from mClientConfigMap map’s
entry.
This could potentially cause use-after-free situation as
notifyClientStopped removes the entry from the map and uses it
later.
To fix this, make a copy of ClientConfigParcel from the mClientConfigMap
map’s entry. Also, update the timestamp of codec::stop
