Add dataSpace to buffer queues; remove old format enums.

- Wire up new dataSpace parameter through buffer queue stack
- Update tests to include the parameter
- Switch eglApi to using dataSpace to indicate sRGB gamma/linear
  difference
- Remove RAW_SENSOR in favor of RAW16
- Remove use of sRGB format enums
- Add default dataspace to buffer queue core
- Add query for default dataspace
