Update documentation for speech APIs.
Makes it clear that the intent and service APIs are likely to stream audio over the network and notes that impact this has on bandwidth and battery life. Also clarifies that the service API should not be used for continuous recognition as a result. The intent API only runs when the activity is in the foreground so I didn't mention continuous recognition for it. Bug: 10674392 Change-Id: Ib5e0c16b3124f4b7d892ef5bd4167f23662d2ca3
