virtchnl: add enumeration for the rxdid format

Support for allowing VF to negotiate the descriptor format requires that
the VF specify which descriptor format to use when requesting Rx queues.
The VF is supposed to request the set of supported formats via the new
VIRTCHNL_OP_GET_SUPPORTED_RXDIDS, and then set one of the supported
formats in the rxdid field of the virtchnl_rxq_info structure.

The virtchnl.h header does not provide an enumeration of the format
values. The existing implementations in the PF directly use the values
from the DDP package.

Make the formats explicit by defining an enumeration of the RXDIDs.
Provide an enumeration for the values as well as the bit positions as
returned by the supported_rxdids data from the
VIRTCHNL_OP_GET_SUPPORTED_RXDIDS.
