hwc2: Fix reading HDR10+ from gralloc metadata

- One variable per_frame_hdr_metadata_ was used to track whether to
  read or avoid from gralloc color metadatas. This variable was set from
  both SetLayerPerFrameMetadata and SetLayerPerFrameMetadataBlobs.
- Since SF calls only SetLayerPerFrameMetadata (w/o support for HDR10+
  thru FW), it avoided reading HDR10+ data from gralloc metadata and
  hence HDR10+ dynamic metadata was not updatedi.
- HDR10+ blob data from FW API has higher priority over gralloc
  metadata, once the FW API sets HDR10+ avoid reading it from gralloc
  metadata as Video HAL doesn't set both.
- Composer must read color metadata from gralloc metadata unless SF sets
  all PerFrameMetaDataBlobs for HDR10+.
