Allow DRM client to pass the FD of an open file to the DRM server.

Browse Source 
This allows a DRM client to open a locally-cached file on behalf of the
DRM server so the DRM server no longer requires the sdcard_r permission
to access the file's metadata.  Specifically, this adds an optional
attribute FileDescriptorKey to the DrmInfoRequest.

This change is dependent on this Widevine CL:
