Hyunjun Ko b41d72b7c5 libs: encoder/context: query region of interest support
Queries if the driver supports "Region of Interest" (ROI) during the config
creation.

  This attribute conveys whether the driver supports region-of-interest (ROI)
  encoding, based on user provided ROI rectangles.  The attribute value is
  partitioned into fields as defined in the VAConfigAttribValEncROI union.

  If ROI encoding is supported, the ROI information is passed to the driver
  using VAEncMiscParameterTypeROI.
