Subject: [PATCH] Mark GenericFrameInfo as an exported symbol

Currently, webrtc can only simulate the GenericDescriptorInfo
based on codec specific info when uses HW encode acceleration.
To provide more accurate description, RTCVideoEncoder in the
chromium blink module needs to fill the generic frame info and
GenericFrameInfo should be marked as exported to chromium.

Bug: chromium:40275246
