BQ: Modify consumer buffer count interfaces

- Rename setDefaultMaxBufferCount() to setMaxBufferCount(). Modify it
  to be hard maximum on the number of buffers that can't be overwritten
  by the producer.
- Enforce the maximum buffer count in setMaxAcquiredBufferCount(),
  setMaxDequeuedBufferCount(), and setAsyncMode().
- Remove mOverrideMaxBufferCount as it's no longer needed since
  overriding is no longer possible.
- Expose setMaxAcquiredBufferCount() in GLConsumer.
- Remove disableAsyncBuffer(), it was only being used for single buffer
  mode. Single buffer mode is now achievable with setMaxBufferCount().
