Query the driver directly for compute units and subslice
Values of device max compute units and max subslice obtained
directly from the driver should be more accurate than our own
ID-based lookup values. This is particularly important when a
single device ID may encompass more than one configuration. If
the driver cannot provide a valid value for the given device,
we fallback on the ID-based lookup value.
This query requires libdrm 2.4.60. For now we will consider
the use of this query to be optional and exclude it from
compilation when building against older libdrm. Later we may
want to consider requiring the query or at least warning
more strongly when it is not supported.
v2: Make feature use conditional on libdrm version (Zhigang).
