intel: Pull anv_i915_query into common code

Browse Source 
We also add a helper which contains the standard query+alloc+query
pattern used by anv_gem_get_engine_info().  The caller is required to
free the pointer.

These are declared static inline not because we care about the
performance of these helpers but because we're going to use them in the
intel_device_info code and we don't want a link dependency.
