hwc2: Derive dataspace on ClientTarget from ColorMode

- The dataspace of the client target depends on the current color mode.
  Clients calls SetClientTarget after prepare, SDM needs dataspace
  information in the Validate phase to set up its pipeline.  Hence
  derive the client target dataspace based on the current color mode.
- Return error if dataspace doesn't match in SetClientTarget
